A.
Before operating microscope,
adjust intensity control located on side of base to the minimum
position.
This should be done prior to each time light is turned on or off. This will extend bulb life.
B.
Insert power plug into 12VDC switching power converter, then insert plug on other end of converter into
power jack on back of microscope base. Note that the 12VDC converter will operate on either 120v or
240v current, 50 hertz or 60 hertz, eliminating the need for any other transformer.
C. Push rocker switch at rear of base to ON position.
D. Rotate intensity dial on illuminator base until image is illuminated.
E.
Adjust intensity of light to match requirements of objective and specimen slide.
F.
Filter: Swing out filter holder has built in frosted filter
– must be in place when using the 4x and 10x
objectives.
G.
In case of equipment malfunction, see “Trouble Shooting” procedures.
2. Adjustment of viewing head:
1.
The three-position sliding rod allows user to easily direct microscope image into desired path.
A. Rod pushed completely into head
– 100% of microscope image is directed into binocular eyepieces.
B. Rod at mid-position (pull or push rod until you feel a gentle click stop)
– 100% of microscope image
is directed to built-in camera.
C. Rod pulled to fully extended position
– 30% of image is directed to binocular eyepieces and 70%
directed to built-in camera.
3. Position sliding rod completely into head to operate microscope.
Interpupillary adjustment of viewing head
A.
Look through microscope and adjust distance between the two eyepiece tubes by grasping the sliding
mounts to left and right of eyepieces and sliding together or apart.
B.
When a full field of view is observed through both tubes, and images blend into one, interpupillary
distance is corrected for your eyes. Check the interpupillary scale and note index reading for future
reference, in case other users will be changing this adjustment from time to time.
C. Adjust the diopter scales, located on each eyepiece tube, to the same numerical value as indicated on
the interpupillary scale. This must be done in order to maintain parfocality of objective lenses. If
interpupillary distance is changed, adjust eyepiece diopters accordingly.
4. Focusing the microscope.
A.
Position the 4x objective lens into the optical path, making sure that lens is properly indexed in its click-
stop position.
