a.
Trinocular head provided with a three position sliding rod to direct light through microscope. The
three position sliding rod (b) allows user to easily direct microscope image into desired path.
1)
Rod pushed completely into head; 100% of microscope image is directed to binocular
eyepieces.
2)
Rod at mid-position (pull or push rod until you feel a gentle click stop), 100% of microscope
image is directed to trinocular port.
3)
Rod pulled to fully extended position; 30% of image directed to binocular eyepieces, 70%
directed to trinocular port.
I.
Eyepieces: Remove the dust caps from eyepiece tubes. Avoid touching any lens surface.
Model 160:
Using the provided .9mm hex allen wrench, loosen the eyepiece locking screw E-1. Insert
eyepiece into the eyepiece tube. Tighten the eyepiece locking screw.
Model 161:
Using the provided .9mm hex allen wrench, loosen the eyepiece locking screw E-1 on inclined
eyepiece tube and vertical eyepiece tube. Insert eyepieces into eyepiece tubes. Tighten the
eyepiece locking screws.
Models 162 and 163: Insert eyepieces into the eyepiece tubes.
J.
Filter: Swing out filter holder and insert 32mm diameter blue filter.
K.
Filter: Insert 45mm neutral filter into the recess located at top of illuminator condenser.
OPERATION
A.
Illumination.
1.
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.
2.
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.
3.
Push rocker switch at rear of base to ON position.
4.
Rotate intensity dial on illuminator base until image is illuminated.
5.
Adjust intensity of light to match requirements of objective and specimen slide.
6.
In case of equipment malfunction, see "Trouble Shooting" procedures.
B. Interpupillary adjustment of viewing head (Models 162 and 163 only)
1.
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.
2.
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.
3.
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.
