A.
Environmental Requirement:
1. Ambient temperature: 5°C to 40°C (41°F to 104°F), Maximum R.H
：
85%.
2. High Temperature will result in a mildewing, dew and even ruinous instrument.
3. Avoid placing the instrument in a dusty environment. When ending your microscope
operation, please cover it with the dust cover.
4. Lay the microscope in a plan and stable position, please.
B.
Input voltage check:
Check the input voltage: be sure the input voltage which signed in the back of the microscope is
consistent with the power supply voltage, or it will bring a serious damage to the instrument.
C.
Eyepiece:
Insert the eyepiece into the eyepiece tube.
D.
Objective:
Adjusting the coarse focus knob until the mechanical stage reaches its lower limit position. Screw
the lowest magnification objective into the nosepiece from the left or the right side, then revolve
the nosepiece clockwise and mount other objectives in the sequence of low to high magnification
E.
Condenser:
The condenser had been installed in the microscope before leaving factory.
F.
Collector:
The collector had been installed and located before leaving factory. The screw-mounted collector
can be taken down by anticlockwise turning.
G.
Filter:
Mount the filter on the iris diaphragm bracket under the condenser if necessary.
6. Operation
1. Insert the eyepiece into the eyepiece tube and revolve the objectives into the nosepiece in sequence
of magnification.
2. Place the specimen in the center of the stage, keeping the cover slip upward, and then nip it with
the specimen holder.
3. Search the image by lower magnification objective, turn the longitudinal and transversal adjustment
knobs which on the mechanical ruler to move the specimen onto the center of the field of view.
Then replace with higher magnification objective, turn the fine focusing knob to sharpen the image.
4. When using 100X oil objective, add the cedar oil between the objective and specimen.
