AUTOMATIC SHUTOFF (Disable)
If no button has been pressed for ten (10) minutes,
the Automatic Shutoff feature will turn the meter off
to preserve battery life.
The automatic shutoff feature setting is overridden
while in the Record Mode. (See the “Record
Mode” section)
To disable the Automatic Shutoff feature, place the
unit into the Record Mode (see the “Record Mode”
section).
PROBE MAINTENANCE
Electrolyte Solution Replacement
If the calibration check does not return the desired
results (see the “Calibration Check” section) or if
the readings are unstable, it may be necessary to
replace the electrolyte solution in the probe head.
1.Unscrew the probe head.
2.Pour out the old electrolyte solution from the
probe head.
3.Fill the probe head with fresh electrolyte
solution.
4.Replace the probe head and tighten securely,
do not overtighten.
ALL OPERATION DIFFICULTIES
If this meter does not function properly for any
reason, replace the batteries with a new, high
quality batteries (see the “Battery Replacement”
section). Low battery power can occasionally
cause an number of “apparent” operational
difficulties. Replacing the batteries with new fresh
batteries will solve most difficulties.

INSTRUCTIONS
BATTERY REPLACEMENT
An erratic display, faint display,
no display, or a battery symbol
appearing on the display are all
indicators that the batteries need
replacement. The battery cover
is located at the bottom of the
unit. While holding the unit upside
down, unscrew the battery cover
by turning it counter-clockwise.
Remove the exhausted batteries
and replace them with four (4)
new AAA alkaline batteries. Make
certain to insert the new batteries
with the proper polarity as indicated by the “+” and
“–” symbols in the battery compartment. Replace
the battery cover and tighten securely.

Diaphragm Replacement
A damaged diaphragm can cause the calibration
check to return incorrect results (see the “Calibration

unstable or inaccurate. The diaphragm may be
damaged if it comes into contact with a solid
object, or is subjected to impacts. The diaphragm
is integrated into the probe head.
