1.1 - ISL Company Profile
We would like to take this opportunity to thank you for choosing ISL product. We are confident that you will be
completely satisfied with your new analyzer and we hope that you continue to call on us for all of your laboratory’s
petroleum testing needs. Before you begin, we ask you to take a few minutes to become acquainted with ISL and its
history.
ISL’s beginnings go back to 1975, when a group of engineers and scientists from the heart of the Northern France’s
petrochemical industry began seeking ways to automate petroleum testing. The neighboring industry served as an
excellent research and development proving ground for their new equipment.
By the end of 70’s, several quality instruments had been developed and were being marketed in Europe under ATPEM
Trademark.
The most famous of these new instruments was the CPP 97, Automatic Cloud and Pour Point analyzer. Introduced in
the early 1980’s, its successor, the CPP97-6, revolutionized cold flow testing enabling up to six tests automatically and
simultaneously.
Adding new automatic instruments each year, ATPEM soon became a world-wide leader in automatic petroleum test
instrumentation. In 1986, they expanded operations, reorganizing into the company now knows as ISL.
Striving to maintain close contact with customers in over 75 countries, ISL has since grown, founded Sales & Service
branches on each continent. With design, marketing, service and support operating together under the ISL roof, the
company reached “a new dimension” in 1993 by obtaining ISO 9002 certification from the BVQI. Working hard to
extend our quality assurance program, we received ISO 9001 certification in 1995.
Though best known for distillation, viscosity testing, cold behavior instrumentation, flash point, evaporation loss,
oxidation, and asphalt testing equipment, ISL's contributions to automated petroleum testing continue to grow. With
more than 10 patents to date, ISL's constant research into new technologies buttresses our precedent for ultimate
precision, performance and safety. The company now offers over 20 Automatic Analyzers for different applications
giving incontestable benefits to its users in increasing of test precision by elimination of operator subjectivity and
human errors, while increasing productivity and reduce operator time with highest level of safety.
A worldwide distribution network supports our customers with quick, efficient service, and our highly knowledgeable
service staff buttresses this relationship, providing solutions to product or application challenges.

NCK2 5G Analyzer product overview
2 - NCK2 5G ANALYZER PRODUCT OVERVIEW
2.1 - General scope
The Noack Volatility Test is used to determine evaporation loss of lubricating oils, an issue of particular importance in
engine lubrication. Portions of an oil can evaporate under high temperature conditions, potentially altering oil
properties such as viscosity. A low Noack score indicates an oil that will maintain its original protective and
performance qualities for a longer amount of time. These oils perform better under heat, translating to better engine
protection, longer oil life, and improved fuel economy.
The original Noack method, now known as “Procedure A” in ASTM D5800, CEC L-40-93 and IP 421 methods, employs
Wood’s Metal in the sample heating process presenting obvious health hazards, thermal transfer errors (due to metal
oxidation and/or crucible lacquering) and weighting errors.
To address these concerns, ISL introduced technology in 1998 that eliminates Wood’s Metal from the Noack test and
directly measures specimen temperature in the crucible. In CEC and ASTM round robins (RR), ISL’s method produced
results with significantly improved precision and consistent correlation to Procedure A on all reference products. The
ISL procedure was subsequently adopted by CEC, ASTM, and IP as “Procedure B” to existing Noack methods.
Periodic Round Robins since 1999 have proven mean values produced by ISL’s Procedure B were remarkably steady
while values produced by the Wood’s Metal Procedure A varied significantly.
ISL’s safe, easy to use NCK2 5G Noack evaporation loss analyzer using this new technology enables the most
precise testing possible to meet increasing QS/QA requirements in full compliance with CEC L-40-93/b, ASTM
D5800/b & IP 421/b methods. Excellent repeatability and reproducibility have been proven through numerous
international round robin programs.
Designed for routine day-to-day work in labs with high sample workloads, the NCK2 5G test initiates with a few simple
keystrokes. The test can be started with either a cold or hot heating block, significantly increasing test productivity as
the operator can immediately start a new test after one completes.
Operation is fully automated. Smart assistance features automatically alert the operator if any test device is not
properly set: an alarm is triggered and the test start is refused if for example the sample probe and/or the crucible is
not installed properly, over-temperature securities are independent for sample and for heating block
The instrument carefully tracks sample temperature and vacuum throughout the test’s duration (flexible programming
of test temperature and duration with programmable audible notification before and at end of test run), providing a
digital display of each and recording the values to memory. Extended local memory capacity, graphic printer
connection and PC link enable powerful, flexible results management.
Optional tube and filter heating kit facilitates testing of waxy products pre-heating interconnection tubing to inhibit
condensation and/or clogging of oil in tubes.
NCK2 5G’s advanced quality control features — including traceable automatic calibrations with lock-out control and
detailed test reports with temperature and vacuum curves plots and tracking numbers of all measuring devices, smart
temperature probe delivered with an engraved serial number with built-in memory ship transmitting ID, offset values
and calibration history to instrument at plug-in — fulfill strict ISO 9000 quality system requirements.

3.2 - The heating block
The crucible is heated by two low-voltage resistive elements mounted on spring ring and an adjustable electric band
heater to ensure a perfect thermal exchange.
The crucible cover includes an insertion port for the temperature measurement probe allowing thus to directly measure
the sample temperature.
3.3 - The glassware unit
The glassware unit provided complies with all standards quoted (see section 2.1 - page I-15).
The glassware unit is equipped with an air filter made of a draining cartridge (coalescer filter). Therefore the air filter
bottle must be regularly empty before the oil reaches the limit.
For the glassware unit assembly instructions, refer to the section 6.2.3.1 page I-24.
The NCK2 5G analyzer is equipped in addition with an efficient and stable built-in electronic vacuum regulation control
device ensuring a constant vacuum of 20 mmH2O ± 0,2 (196Pa) in the oil vapor extraction circuit.
CAUTION! Regularly empty the air filter bottle of the glassware unit: if the oil in the air filter bottle exceeds the maximal
limit, then it will be able to infiltrate in the vacuum circuit that it will risk to seriously damage the vacuum pump.
3.4 - Optional equipment
3.4.1 - Peclet type manometer
A relative pressure transducer allowing a visual reading of the depressure value in the vacuum circuit can be added to
the standard equipment. Refer to the chapter 6 - Unpacking and installation paragraph 6.2.3.2 page I-25 for
explanation on Peclet type manometer mounting.
3.4.2 - Tube and filter heating kit
The optional tube and filter heating kit enables interconnection tube and filter to be heated in order to reduce waxy
product clogging and condensation problems to be avoided.
It is firstly made off glass interconnection tubes around which an electric wire is wind and wrapped covered with a
casing and secondly, off a filter stand equipped in its center with an heating cartridge.
3.4.3 - Balance
A balance can be connected to the NCK2 5G analyzer if this balance is equipped with an RS 232C serial port
(DB25/DB9 cable generally supplied with the balance). Connection of a balance will allow you a semi-automatic
acquisition of the mass of the empty cup as well as the mass of the cup containing the sample or ever an acquisition of
the initial mass and the final mass of the sample only. Thus you will suppress keying errors but also carry out a
monitoring of the mass of the empty cup in order to detect for example cleaning problems on the crucible for reliable
results.
The balance is connected on the SERVICE port of the analyzer (refer to the section 6.3.6 - page I-28). Most balances
equipped with an RS 232C serial port can be used on condition the analyzer links signals are coordinated with those of
the balance (refer to the section ).

Description of the NCK2 5G analyzer
3.4.4 - Draft protection kit
Noack method requires that the apparatus be operated in a draft free environment. One way to achieve a draft free
environment even if the analyzer operates in a hood is to install a draft protection shield to isolate the heating block
thus greatly reducing the air flow immediately around the sample while allowing sufficient thermal exchange.
A draft protection kit is available as option (consult the spare part list; DOCV240X200). This protection shield is
installed very simply on the heating block (refer to the section 6.2.3.4 page I-25).

Two things must be noted here:
When the apparatus is switched on, the test run screen, Figure 3 above, is displayed after selecting the
language.
This does not mean that this screen comes hierarchically after the welcome screen (see PART III - section 2 Main Menu page III-47).
This is merely an arrangement designed to speed up access to the test menus.
The NCK2 5G Run/Start menu includes the following information:
• Prod : type of product tested (selected by default at switching on; refer to the PART III - section 6.2 - Analyzer
setup : the Run menu page III-58)
• ID : sample identification
• Method : name of the method used (parameter linked to the selected product)
• Simul : test temperature and duration (parameters linked to the selected method)

3 - PREPARING THE SAMPLE AND THE ANALYZER
3.1 - Checking the assembly
Check that the various components of the glassware unit are clean and assembled correctly (for assembly details,
see PART I - section 6.2.3.1 page I-24).
3.2 - Cleaning
Check that the residual material in the bottles and filter from previous tests is below the line indicating the authorized
maximum level.
CAUTION! Regularly empty the air filter bottle of the glassware unit: if the oil in the air filter bottle exceeds the maximal
limit, then it will be able to infiltrate in the vacuum circuit that it will risk to seriously damage the vacuum pump.
Clean the crucible cover and the extraction tube of the crucible cover with a cleaning solvent (refer to the “Reagents
and Materials” section of the standard method used to know the solvents recommended) then check the cover
nozzle and the extraction tube for clogging with lacquer or residual material: pass the reamer through each nozzle
and the ball through the extraction tube (the reamer and the ball supplied comply with the standards quoted in PART
I - paragraph 2.1 - page I-15)

5 - TEST LAUNCHING
When all the test identification steps described previously are finished, withdraw a product sample of 65g ± 0.1g (to the
nearest 0.01g) following instructions of the standard method.
Note these steps are optional. Actually it is possible to start the test with the product selected by default if it is suitable
or as soon as another product has been selected.
ATTENTION! Throughout the test, the crucible must be handled with care so as to avoid any liquid splashing onto
the inside of the crucible cover.
5.1 - Manual keying of masses
If the manual keying of masses is used:
• Weigh the empty cup without its cover on a balance complying with the standard method being used and note the
mass of the empty cup.
• Set the balance to zero and withdraw a product sample of 65g ± 0.1g (to the nearest 0.01g) following instructions of
the standard method.
• Note the initial mass of the sample withdrawn.
From the NCK2 5G Run/Start menu (see Diagram 4 page II-31):
• Press the key “PREPARE THE RUN”; the following screen is displayed:

Figure 10 : Screen 1 of the NCK2 5G/Prepare the Run menu.
• Press the EMPTY CUP key and from the NUMERIC KEYPAD enter the mass of the empty cup read. Validate with the
ENTER key of the keyboard.
Note: This information is not compulsory: actually only the initial mass and the final mass of the sample are
necessary to calculate the Noack volatility. But if this information is registered in the analyzer, at the end of test you
should weigh the cup + the final mass of the sample, the analyzer will deduce the final mass of the sample alone
(doing this avoids tarring the balance after weighing the empty cup and make it unusable during all the test).
• Press the SAMPLE MASS key and enter either:
the initial mass of the sample withdrawn only if the balance has been tarred.
or the mass of the empty cup + the initial mass of the sample withdrawn if the mass of the empty cup has been
registered.
• Validate with the ENTER on the KEYBOARD.
5.2 - Semi-automatic keying of masses
If one balance is connected to the analyzer, proceed as follows:
• From the NCK2 5G Run/Start menu (see Diagram 4 page II-31), press the PREPARE THE RUN key, the screen 1 of
the NCK2 5G Run/Prepare the Run menu is displayed (see Figure 10 above).
• Press the BALANCE key to activate the semi-automatic weighing function: the dedicated field becomes “ON”.
Note: The analyzer and the balance must have been configured when they were installed (refer to the section 6.8 page III-62). The setup menu of the balance is also accessible from the acquisition screen of masses via the Setup
menu (see below).
• Press the EMPTY CUP key to carry out the weighing of the mass of the empty cup. The following screen appears:

unit
This screen contains the following KEYS and menus:
CANCEL : Return to the screen 1 of the NCK2 5G Run/Prepar. menu without saving the measure
OK: Validation of the measure and return to the screen 1 of the NCK2 5G Run/Prepar. menu
Setup: Accessing to the balance setup menu (refer to the section 6.8 - page III-62)
Note: The mass of the empty cup is not compulsory: actually only the initial mass and the final mass of the sample are
necessary to calculate the Noack volatility. But if this information is registered in the analyzer, at the end of test you
should weigh the cup + the final mass of the sample, the analyzer will deduce the final mass of the sample alone
(doing this avoids tarring the balance after weighing the empty cup and make it unusable during all the test).
• When the measure is deciphered and displayed in the dedicated field, press the OK key to validate the acquisition
and to return to the previous screen. The mass measured appears then in the dedicated field above the Empty Cup
menu.
Note: If it is not the case, check the configuration of the RS 232C interface of the analyzer SERVICE link (refer to
the section 6.8 - page III-62).
If no message is displayed, check the compatibility of connectors (refer to the Appendix C page 105).
• Set the balance to zero and withdraw a product sample of 65g ± 0.1g (to the nearest 0.01g) following instructions of
the standard method.
• Press the SAMPLE MASS key and proceed as explained above for the acquisition of the initial mass of the sample
withdrawn. Measure:
Either the initial mass of the sample withdrawn only if the balance has been tarred.
or the mass of the empty cup + the initial mass of the sample withdrawn if the mass of the empty cup has been
registered.
5.3 - Cover identifying

5.4 - Setting-up the sample on the test bench
5.4.1 - Setting the cover in place
• Place the cover on the cup containing the sample.
• Screw on the cover tightly with the spanner removal cover and the cup assembling clamp provided. In the absence
of any seal between the cover and the cup, the precision of your measurements will depend on the cup/cover
interface.
5.4.2 - Setting-up the crucible in the heating block
• Lower the lever located on the right-hand side of the test unit so as to open the adjustable electric band heater.
• Place the crucible in the heating block reservation while holding down the lever on the right-hand side.
• Give the crucible a press then turn it to the left to lock it (securing the flange under the screw heads) and ensure
close contact with the lower part of the cup and the spring-mounted heating element.
• Adjust the final position of the crucible cover extraction tube so that is located in front of the right arm of the glass Ypiece then release the locking lever (refer to the PART I - section 6.2.3.1 Assembling the glassware unit page I-24).
• Connect the extraction tube to the right arm of the glass Y-piece and secure the connection with the clamping
device. The crucible cover extraction tube and the arm of the Y-piece must be properly aligned.
Note: Make sure not to unscrew the cover when locking the crucible onto the heating block.
• Remove the probe from its sheath and insert it in the orifice provided for the purpose on the crucible cover.
• Lock the probe in place with a quarter turn to the right (bayonet system).
Caution! Following a test, the heating block stays hot.
If you wish to perform another test while the heating block is still hot, start the test as soon as the crucible is set in
place.
5.5 - Starting the test
The analyzer then checks the various starting conditions then the test is started, and this is confirmed by the green
LED on the STOP/TEST key (see PART I - section 4.1.3 - page I-21). The pump is immediately switch on and the Run

The Central Processing Unit (CPU) controls the sample temperature, the test duration, the vacuum and the heating.
The sample is heated to 245,2 °C with the temperature profile recorded in the specimen when tested with a Woods
metal apparatus (1 h at 250°C) with automatic test duration compensation. The automatic test duration compensation
is used because a test may be started with a heating block at room temperature or at hot temperature when several
tests are carried without cooling phase. The CPU automatically adjusts the pressure differential of 20 ± 0,2 mm. These
conditions can be checked with the printed report : the graphs of the sample temperature and the vacuum recorded
during the test are printed.

III - section 5 - Printing and printer setup: the « print » menu page III-55).
• Leave the crucible to cool for 30 min then remove it from the bath, dry it with paper or cloths (it is recommended to
wear insulated gloves).
When this time is passed, carefully remove the crucible cover, making sure that the sample never comes in contact
with the inside of the cover.
ATTENTION! To avoid splashing any liquid, the crucible must be handled with care when unscrewing
the cover.

6.4 - Calculating of the NOACK volatility
The NOACK volatility percentage per unit mass is expressed by the following equation:
M1 M 2
• 100
M1
where
M1 = sample initial mass
M2 = sample final mass
With the NCK2 5G analyzer the volatility of the product tested can be calculated automatically. If the mass of the
empty crucible had been registered at test starting, the cup is weighed again without its cover. If only the initial mass of
the sample had been registered, only the final mass of the sample will be entered. After the final mass of the sample is
registered in the analyzer, the NOACK volatility calculation can begin.
If the cooling time has set to a time superior to 0, the following screen automatically appears at the end of the time
programmed or when the WEIGHT key from the end of test screen is pressed (see Figure 16 page II-41) allowing you
to enter the final mass of the sample tested (with or without crucible) or to register the mass measured with a
balance connected to the analyzer:

• The product used to carry out the test
• The depression value.
• The test duration
• The test identifying name
• The method used to carry out the test
• The reference of the temperature probe.
• The serial number of the temperature probe
• The operator-identifying name.
• The serial number of the crucible.
• The atmospheric pressure value
• The specimen mass M1 before the test (to the nearest 0,01g).
• The specimen mass M2 after the test.
• The percentage of NOACK volatility obtained.

6.6 - NCK2 5G
PC communications : the PC Link and RS232 menus
The NCK2 5G is an « open » apparatus in more ways than one. Not only is it fully parameterizable, it can also
communicate with a PC through the following facilities :
®
• the RS 232C link (Alan network Input/Output ports connection through a special adapter)
• the RS 485 link (connection to the Alan® network)
• the Service port (rear panel of the analyzer).
Each of these communication modes is specialized as follows :
• The RS 232C link enables the NCK2 5G to send among others test results to a PC or any other computer system
(LIMS for example).
• The RS485 link enable the NCK2 5G to be connected to the Alan® network
The Alan network enable if necessary several analyzers to be linked (NCK2 5G and others) between us and to be
controlled from the host computer.
• The service port is used for downloading the control software and downloading/uploading the contents of memory
for updating or data backup (refer to the section 4.3 - File download command: the ISL UDS menu page IV-82).
Parameters relating to each of these communication mode are explained below.
6.6.1 - RS 232C link setup : the RS232 menu
If the RS 232 C link, is selected as the communication mode you will first need the appropriate adapter (see packaging
list) shipped with the apparatus. This adapter has two RS 485 connectors on one side which must both be connected
®
to the Input/Output ports of the analyzer’s Alan network and an RS 232C connector on the other side, which is
connected to the PC (refer to the section 6.3.5.1 page I-26).
When the adapter has been connected, the apparatus automatically detects the presence of an RS 232C link :
When the RS 232 adapter is detected :
• The RS 232C link is declared « in service »
• The RS 485 link is declared « out of service »
The parameters relating to this communication mode are presented in the table below :

Some balances which have 2 ranges and 2 accuracy send the number for the 10 mg enclosed with ( ) that disturbs the
decoding of the value. The FILTER key will allow the characters unconnected with the measure to be filtered.
Ex: the message “ + 16.4 (5) g “ without filter will become “16.45g” with filter
Moreover, the message received can not contain more than 30 characters. If the message is longer, it will not be correctly
decoded. In this case, use the FILTER key to limit the size of the message received: the characters unconnected with the
measures will be deleted.
UNIT key:
When the CR character is received, the message is decoded by beginning from the end.
Firstly, research of the unit data (g, mg or kg)
Secondly, research of the value and the sign
As long as no unit is decoded, the value will not be displayed. In case of problem, the UNIT key will allow to indicate how the
unit must be decoded, the value being always supposed to be on the left.

3 to 30: Indicate the position of the unit in the message with 0 = 1er character on the left (the unit will be researched in the 6
characters located on the right).
0 to 2: Message send with the unit (0=kg, 1=mg, 2=g). This function will be useful for certain old balances which can not
send the unit with the measure.
Table 12: Balance menu screens
Note: The balance will also be programmed to send the mass measured, preferably when the mass is steady.
Programming of the balance:
Note: The stop bit is not programmable on the NCK2 5G. So check the balance send just 1 stop bit.
The NCK2 5G only requests messages for mass measurement. If it receives other messages following, the mass will
not be displayed. So the balance must be programmed to only send the mass.
Moreover, as long as a unit is not decoded, the value is not displayed. With Sartorius and Precisa balances in
“continue sending” mode, as long as the value is not steady, the message is sent without unit, the unit only appears
when the measure is steady. Associated with the NCK2 5G, the value is displayed when the measure is steady, so this
function is very interesting. It is possible to program the most balances to send messages only when the measure is
steady or by pressing a key on the balance.
Note: The line “message received” of the mass acquisition screen allows the link diagnostic to be made (refer to
the section 5.2 - page II-36).
Refer to the Appendix C page 105 for the RS 232C link features of the analyzer SERVICE port and some examples of
analyzer setup for some balances.

7.1 - Types of alarm
There are 2 types of alarm
• Failure alarms – continuous buzzer,
• Warning alarms - discontinuous buzzer,
See PART I - section 5 - NCK2 5G system safety features page I-22 for more details.
7.2 - Displaying alarms, stopping the buzzer

Press the ACQUIT key to stop the buzzer and return to the previous screen. Note that the red LED on the ALARM
STOP key stays on for as long as the failure persists, even if the alarm has been acknowledged.
Review: to display the alarm historical.
7.3 - Alarm processing
Certain alarm cases present a danger. This is why most failure settings switch the analyzer into idle status, the pump
feed is cut out and the heating stopped.
However, this is not to say that this type of apparatus is hazard-free or that if the analyzer fails to go into idle status the
operator and/or analyzer are not in danger. It is important always to check what is going on whenever an alarm is
triggered.
Attention! Generally when the alarm buzzer is triggered, the operator must display the cause and ensure that
everything is working correctly.
For example, owing to a faulty component an alarm that normally should place the apparatus in idle mode fails to do
so. In that case, the operator must intervene by switching off the analyzer.
7.4 - Failure alarms
7.4.1 - Memory failure
When the apparatus is switched on, the microprocessor checks the content of the different memories. If there is an
error it will be detected by calculation and comparison with the checksum.
7.4.1.1. “Software memory (PROM)” failure
If this failure is reported, switch the apparatus off then on again. If the failure persists, contact the ISL Customer
Service.
7.4.1.2. “Data memory (Ram)” failure
If this failure is reported, switch the apparatus off then on again. If the failure persists, contact the ISL Customer
Service.

NCK2 5G User and Maintenance Manual
DOCV240A011-F
Alarms treatment
7.4.1.3. “Safe memory (NVM)” failure
The battery for backing up the non-volatile back-up memory (NVRAM) has a service life of 7 to 8 years. This alarm
may therefore be due to a faulty battery.
The content of the RAM memory saved where the analyzer parameters are stored is checked by the microprocessor. If
there is an error, the analyzer goes automatically into « download » mode so that the contents of the RAM memory
saved can be restored by loading a backup file from a PC.
For this purpose, a diskette containing the internal parameter factory settings (necessary if memory has not been
recently uploaded) and a PC up/download program are shipped with the standard version of the analyzer. See PART
IV - section 4.3 - File download command: the ISL UDS menu page IV-82 on how to load the analyzer parameters.
Note: So as to have an up-to-date copy of the analyzer’s internal parameters always to hand, it is advisable to
upload the internal parameters to the PC during routine maintenance operations.
Use a new file name each time this operation is performed. Do not use the internal parameter file name on the original
diskette supplied with the analyzer.
7.4.2 - “Signal conditioning (A/D converter)” failure
This failure is reported upon detection of no dialogue between the CPU and the A/D converter. Switch the apparatus
off then on again. If the failure persists, contact the ISL Customer Service.
7.4.3 - “Low battery” failure
The system keeps a permanent check on this failure. If the failure is reported :
Do not switch off the analyzer as this will delete any stored data.
Print or upload to a PC file the analyzer parameters contained in the RAM memory saved:
Uploading : see PART IV - section 4.3 - File download command: the ISL UDS menu page IV-82 on how to
load the analyzer parameters.
Printing: of the context environment (test parameters for the different products, see 3 - Setup and printing of test
conditions: the « Run Environment » page III-49) and internal parameters (sample temperature adjustment,
frequency of adjustments, pressure adjustment…; refer to the PART IV - section 3 - The Service menu of the
main printing menu page IV-79).
Switch off the analyzer and call for a qualified technician to change the battery.
Note: Regular uploading of the internal parameters must be programmed as part of the apparatus maintenance
procedure. Use a new filename (e.g. with the current date in the name- PIDDMMYY. NVM). This way the latest
version of the internal parameters will be saved to a file.
7.4.4 - “Sample temperature safety” failure
The system checks for this failure at the start of a test. The alarm is triggered if the sample temperature is higher than
the setpoint temperature + 5%. The current test is stopped.
This failure is also indicated if the temperature probe is disconnected or faulty.
7.4.5 - “Heating circuit or missing probe” failure
The system checks for this failure during a test. It is reported:
If the « setpoint temperature – 5% » is not reached after 15 min.
As long as the temperature is lower than the « setpoint temperature – 10% », 2 min after the heating power has
reached a power higher than 60%, if the heating rate is not higher than 5°C/mn.
If this failure is reported, the test is stopped.
Check the probe positioning in the crucible then check the crucible positioning in the heating block.
7.4.6 - « Check vacuum measurement system » failure
The system checks for this failure 30 s after the start of a test. It is reported if the pressure in the system is lower than
10 mmH2O.
If this failure is reported, the test is stopped. Check tightness of the various circuit elements.
7.4.7 - « Depressure measurement safety » failure
The system checks for this failure in permanence. It is reported if the depressure in the vacuum circuit is higher than or
equal to 25 mmH2O.
If this failure is reported, the test is stopped.
7.4.8 - “Depressure out of limits” failure
During testing, the system checks the depressure value in the vacuum circuit. The alarm is triggered if this value falls
outside the programmed limits for 5s (see section 6.3 - Alarm setup : the Alarms page III-58 of this section).
The test is not stopped but the alarm is stored and displayed in the form of a binary message on the ticket printed for
the result, which will be marked with an asterisk (see section 4 - Displaying and printing results: the Results menu
page III-53).

It is necessary to open the leak solenoid valve before starting the pump: the pressure should increase dramatically
with the result that the alarm “Depressure measurement safety” would be triggered (refer to the chapter 7 - Alarms
page III-64). So, when the pump is controlled, the analyzer gives a default values of 160 opening points to the leak
solenoid valve (this value is modifiable).

2.1 - Sample correction table : the Sample Probe menu
The sample temperature probe supplied with the NCK2 5G analyzer is equipped with a built-in memory circuit including
up to 5 correction points. The apparatus automatically detects the presence of probe with memory.
If NCK2 probe (with no built-in memory) is used, correction points will be registered in the analyzer parameters
memory and each time the probe is changed, probe correction points must be entered.
The Sample Probe menu enable the correction table of the sample temperature measurement probe to be updated if
the probe is not equipped with a memory.
The sample temperature displayed take this table into account in test only. The correction is calculated according to
the temperature setpoint value then it is applied as soon as the test starts.

To do so enables a diagnosis to be made easier.
3.2 - Internal parameters
A number of internal parameters are stored in the non-volatile memory. They are controlled by the microprocessor with
a code checksum stored in the memory.
These internal parameters relate to:
Settings values
Configuration values
The analyzer configuration
One of the first operations we recommend on receiving your analyzer or before any modification is to print out all
service parameters. Keep this list to resort to it in case of problem.
Refer to Appendix A section 8 - page appendix 94 for a printing out example of the analyzer internal parameters.
A copy of the service parameters is also delivered with the analyzer NCK2 5G, but it should be kept safe by the person
in charge of the laboratory.

4.3 - File download command: the ISL UDS menu
The basic analyzer is delivered as standard with the “ISL UDS” PC program for data uploading (backup on a PC) /
downloading (from a PC towards the analyzer):
You can download on the analyzer:
An update of the analyzer software (using an update diskette or from a downloaded file)
Run environments (parameters of prestored products and operator names)
The whole content of the Nvm memory (analyzer internal parameters, run environments and results)
You can upload:
Run environments (parameters of prestored products and operator names)
The whole content of the memory (analyzer internal parameters, run environments and results)
Downloading / Uploading is made via the analyzer “SERVICE” port at the back of the analyzer (see Picture 6 page I28). An external connection cable is standard equipment for data flow between PC and analyzer.
Downloading/Uploading is a function special to this analyzer. The analyzer is in this mode, either:
• By automatic detection of a download request or,
• By an explicit request made by the operator via the analyzer keyboard.
Caution: Once the analyzer is in this mode, it can not quit it using the keyboard: Downloading causes memory
loss. If an error is made, it is better to let the downloading continue, and then download again. If the operator
stops the analyzer during downloading, the next time the analyzer is powered up it will automatically detect that a
transfer is needed.
4.3.1 - Transfer procedure
The analyzer goes into download mode either automatically, or requested by the user. It waits for a PC transmission.
When the downloading software runs on the PC, it sends a specific message to the analyzer.
In replying to this message, the analyzer indicates the type of downloading required, followed by a safety sequence.
The PC then sends data, which is processed by the analyzer.
When the PC software considers the downloading is finished, it validates this with a signal to the analyzer.
4.3.2 - Installation and start-up of the downloading program on the PC

5 - NCK2 5G MAINTENANCE
5.1 - Periodic maintenance
The bottles stopper seals and the seal of the crucible lid extraction tube should be replaced regularly. The ideal time
intervals depends on the analyzer environment, its frequency of use and the kind of the products tested. The optimal
time intervals will only come from experience.
The minimum checks to perform are in particular the sample temperature and differential pressure measurement. They
should be performed at regular intervals and at least once yearly.
Regular uploading of the content of the non-volatile backup memory must be planed as part of the analyzer
maintenance procedure (and as soon as an internal parameter is modified; regulation value or setting value).
This way the latest version of the internal parameters will be saved to a file (refer to the section 4.3 - page IV-82).
5.1.1 - Bottle stopper seal
Each stopper of glassware unit bottles is equipped with a seal M010115 ensuring tightness in the vacuum circuit ((F),
Diagram 2 page I-24).
• Loosen the stopper slightly at each end of the glass elbow tube concerned.
• Remove the glass elbow tube then completely unscrew the stopper.
• Remove the ferrule with the seal from the stopper.
• Remove the seal from the ferrule and replace it.
• To reassemble the stopper, proceed in the reverse order. Pay attention to the mounting sense of the metallic
ferrule:

5.1.3 - Draining cartridge of the air filter
The glassware unit is equipped with an air filter made of a draining cartridge (coalescer filter). Therefore the air filter
bottle must be regularly empty before the oil reaches the limit.
Nota: If the oil in the air filter bottle exceeds the maximal limit, then it will be able to infiltrate in the vacuum circuit
and it will risk to seriously damage the vacuum pump.
It is not necessary to change the draining cartridge of the air filter before it is totally inefficient. This will be indicated by
the alarm “Depressure measurement safety” detecting an obstacle in the vacuum circuit causing an abnormal
increasing of the depressure. Thus you will be able to determine the optimum economic life of the draining cartridge
according to the analyzer environment.
Caution, this problem can also occur if the product tested clogs in the tubes of the glassware unit. In this case, use the
tube and filter heating kit (refer to the section 3.4.2 - page I-18).

Comments
Transmitted messages are sent without any way to stop them from
the host computer.
However, a special parameter ("Time between two messages") in the
ISL analyzers allows to define a pause between to successive message
from 0.0 s to 10.0 s (by step of 0.1 s)
Note : This time is applied between 2 entire messages (not between
characters)
Existing signals defined in the RS232 interface standard are used to
control the transmission.
Connect the host computer serial RTS signal to the analyzer CTS
signal.
When the input buffer of the host computer is full, the RTS signal
changes its state. Seeing its CTS signal changing, the analyzer stops
transmission until CTS changes again.
Note: This hardware handshake is controlled by the communication
hardware devices and can stop / restart transmission between any
characters
This well-known handshake is qualified as "software protocol"
because it is controlled by the host computer reception software to
control the data flow.
If the software needs time to process the last incoming message, it can
send the Xoff character to the analyzer which immediately stops the
transmission, until it receives from the host computer the Xon
character.
This is a full protocol. It allows flow control and data
acknowledgment.
The transmission is fully controlled by the host computer which must
send a ENQ (enquiry) character. Any message must be acknowledged
by the host computer by sending a ACK character.
Note : There is no need to define a time between messages because
the message sequencing keeps pace with the ENQs sent by the host
computer.

Xoff = 13H

ENQ / ACK protocol details
4 - ENQ / ACK PROTOCOL DETAILS
All messages from the analyzer must be acknowledged by the host computer.
Should communication fail, only the host computer can decide whether or not to abort transmission.
Analyzer response time on receiving ENQ:
Waiting time for message acknowledgment:
Results transfer delay after end of test (delay for ENQ) :

not limited
not limited (end with ACK or EOT reception)
Request, reception and acknowledgement of results
The host computer uses the ENQ code (05H) to ask the analyzer if any results are ready to be sent.
If the analyzer has no results to send, it replies ACK (06H). the host computer does not have to reply to this ACK.
ANALYZER
No result available
HOST COMPUTER
ENQ
No result ACK
If the analyzer has results, it starts their transmission.
On receiving the message, the host computer must check it (checksum) and must reply ACK (06H) or NAK (15H),
depending on whether the message was correct or not.
If there are several fruitless communications, the host computer may decide to abort transmission by sending an EOT
(04H) character.

Contents
Transmitted...
Results
See messages R or D1 and D2 below
Run context
See message C1, C2 and M below
Always (R or D1 and D2 according to the
RS 232 link setup)
If defined in the RS232 link setup
To be transmitted, a result must be validated (a result can not be validated if the Noack volatility calculation has not
been performed).
manual validation must be performed at the analyzer level (refer to the section 4 - page III-53,). The transmission
is only possible after the validation.
automatic validation can be set in the RS232 link setup (refer to the section 6.6.1 - page III-60, screen 2 of the RS
232 menu.
5.1 - Message format
Messages are in ASCII code.
Character strings are enclosed within “ “ (double quotes).
They start with an opening bracket (
They finish with
a closing bracket ) , 2 characters CK , and the characters : CR, LF and EOT
CK (2 characters) = checksum = the 2 least significant digits (expressed in ASCII) of the result of the
hexadecimal sum of all the preceding characters, including the brackets.
CR (1 non printable character) = Carriage Return = 0Dh
LF (1 non printable character) = Line Feed = 0Ah
EOT (1 non printable character) = End Of Transmission character, programmable in the RS232 setup menu (If =
0 , there is no end of transmission character).
The value 999 indicates that the field is not being used (reserved for a future use).
5.2 - Result message
As indicated above, if the transmission of data on the RS 232C link has been validated (automatic or manual
validation), the result message is systematically transmitted.
According to the link setup, it is sent under characters string corresponding to the information indicated on the result
ticket, the message R, or it is sent under characters string corresponding to the points coordinates forming the result
curve printed under graphic form, the message D.
Temperatures expressed in °C or °F, corrected or not by barometric correction, depending on the product
programmed.

RS 232C Interface features of the SERVICE link
As explained in the section NCK2 5G analyzer presentation, it is possible to connect a balance to the analyzer if the
balance is equipped with an RS 232C serial port (cable DB25/DB9 generally supplied with the balance) for a semiautomatic acquisition of masses.
The balance is connected to the analyzer via the SERVICE port located on the rear panel (refer to the section 6.3.3 page I-26).
Most of balances equipped with an RS 232C serial port can be used on condition the signals of the analyzer link to be
coordinated with those of the balance link (refer to the section 6.8 - page III-62). The outlet connector broaching of the
balance must also be checked to correspond with the RS 232C connector broaching of the NCK2 5G analyzer
SERVICE port.

3 - EXAMPLES OF SERVICE LINK SETTINGS FOR DIFFERENT BRANDS OF BALANCES
The RS 232C interface of the analyzer SERVICE port must be coordinated with the interface of the balance (refer to
the manual of the manufacturer of the balance to know the factory setting).
For example, you will find in the following section some possible setup of the analyzer according to factory settings of
different balances.
Note: Refer to the section 6.8 - Link interface setup of the balance: the Balance menu page III-62 for the
explanation of the different setup parameters of the link.
