Operation
Remove components from package. Identify all parts before assembling. Tighten
the knob on the stand to prevent the elevator from sliding down.
1. Environment Requirement:
Dry dust free room temperature between –5---+40 degrees Celsius.
2. Illumination Control:
Plug in the power cord into the outlet. Refer to the following table for
illumination styles. For microscopes with dimmer control the brightness of the
illumination can be adjusted.
3. Select the Stage:
a. The frost glass stage is placed on the base and is xed with a screw,
it is used when a transparent specimen is being observed, and please use
transmitted illumination.
b. Black and white stage is kept in the packing as an accessory. When it
is to be used, take off the glass stage and place the black and white stage
on the base. Normally the white side is upward. If the specimen is white or
in other bright colors, use the black side to improve the contrast with only
incident illumination.
4. Placement of Specimen:
Place the clean specimen in the center of the stage and x it with clippers if
necessary.
5. Use of Rubber Eye-Guard:
One pair of rubber eye guards is contained in the packing. They are used to
prevent the extra light from entering the eyepieces, to improve visibility.
6. Focusing, Diopter, and Adjusting Interpupillary Distance:
a. Adjust the focusing rack by loosening the lock-screw located behind the
pillar stand. Move the entire focusing rack so that the image is roughly in
focus, then re-tighten the lock-screw.

b. Begin focusing by rst looking with one eye through the eye tube without
the diopter. Close your other eye. Bring the image into focus using the
focusing knob.
c. Once the image is focused through the rst eye, look only through the
other eyepiece, turning the diopter until the image is as clear as through
the other side. Open both eyes and adjust the interpupillary distance until
one clear image is seen.
d. As you switch magnication levels, you may also need to re-center the
specimen, and/or refocus the image.
7. Objective Power Switch:
To change the magnication setting of the objectives, use the rotary case
housing 180 digress it click into place.
Note: In order to observe the specimen easily use the lower magnication
objective rst. Then, by rotating the case, the magnication can be changed.
