Lamp Replacement and General Maintenance:
Warning: Unplug the power cord from the wall outlet, or remove
batteries from the microscope, and allow the lamp to cool down
before replacing!
Unscrew the four rubber feet on the bottom of the base and remove
the bulb from the lamp socket. Insert replacement bulb into lamp
socket, making sure to not touch the bulb with your bare hands. Use
a tissue or cloth, oils from the skin will lessen the life of the bulb. To
order replacement bulbs, contact Fisher Education Customer Service
at 1-800-955-1177.
Introduction:
This biological microscope is well designed and sturdily built. It has high quality optics
and precision mechanics which meet the requirements of senior high schools. All objectives are parfocal, parcentered, the 40x and 100x objectives are spring loaded which
prevents damage to the specimen and/or objective. The head rotates 360 o.

Assembly:
Interpupillary Distance Adjustment:
The head is easily attached to the microscope body by loosening the thumbscrew, sliding
the head onto the stand, and tightening the thumb screw. Next, remove the eyepieces from
the protective paper, and slide into the eyetube(s).
Interpupillary adjustment, the distance between the eyepieces, is made through a “folding”
action that is built into the head. Place a specimen slide on the stage and focus on it using
the 10X objective. While looking through the eyepieces, move the eyepieces together or
apart as necessary so the field appears as one circle and viewing is comfortable. The
index on the head indicates the interpupillary distance.
Setting up your micoscope:
Connect the power cord to an outlet and turn on the power switch. Note: some models
are cordless, and do not require an electrical outlet for use. Open the diaphragm underneath the stage to its full open position. Place your slide into the slide hoder and look at
the slide through the eyepieces.
Safety Stop/Up Stop Adjustment:
The microscope is also equipped with a safety stop or up-stop. When set, this will limit
the uppermost travel position of the stage. When used properly, the up-stop control will
prevent the microscope slide from making contact with the tip of the objective. It can also
be used to simplify focusing. After focusing on the specimen with the coarse adjustment
knob, adjust the up-stop to set the upper limit on the coarse adjustment movement. After
changing specimens, refocusing is easily accomplished by turning the coarse adjustment
knob to the up-stop position, then making fine adjustments with the fine focus adjustment
knob.
To set this control:
1. Place a slide with a cover slip on the stage, and swing the 100X objective into position.
2. Look carefully at the gap between the tip of the objective and the coverslip. Slowly raise
the stage with the coarse focus control knob until the gap is small, then use the fine
focus control knob until the objective is VERY close to, or just touching the cover slip.
3. Locate the safety stop (see microscope diagram, page 2). First loosen the smaller
knurled nut. Then turn the larger knurled nut one-quarter turn at a time. Turn the
coarse focusing knob until the desired height it set. If the stage will not go high enough,
loosed the larger knurled nut another one-quarter turn, and repeat until the correct height
is set. Once this is done, tighten the smaller knurled nut to lock in the stage stop.

Diopter Adjustment:
Diopter adjustment allows for proper optical correction for each individual’s eyesight.
1. Looking through the right eyepiece with your right eye, focus on the specimen slide
using the coarse and fine adjustment knobs.
2. Looking through the left eyepiece with your left eye, turn the Diopter Adjustment ring to
where the specimen is in focus.
Using your micoscope:
Select the 4x objective to “scan” and locate the image of your specimen, and then
switch to the 10x objective. Use the coarse and fine adjustments to bring the specimen
into focus. Now switch to the 40x objective and focus using the fine focus knob. View
the image with the 40x objective as there is less depth of focus and this will assure
parfocality when you use a lower power objective.
The S90005 microscopes include an iris diaphragm located on the condensor below the
stage. The iris is adjustable, and controls the amount and angle of light going to the specimen. This is used to get the best contrast possible.
General Maintenance:
When not in use, protect the instrument with the dust cover provided.
Use filtered air to remove dust particles, and lens cleaner on a Q-tip for lens cleaning.
The 40x objective is a “dry” objective. Do not use immersion oil as it will destroy the
lens and void the warranty.
