V. INSTALLATON:
1. Working environment:
1) Indoor temperature: 0℃~40℃, the maximum relative humidity: 85%.
2) The microscope will be mildewed or damaged in the environment of high temperature
3) Don’t put microscope in the dusty environment. Please cover it with ethene plastic bag,
4) Please put microscope in the plate place.
2. Transmission adapter:
Put the transmission adapter on microscope, when screw is connect with orientation slot of the
adapter, tighten the fixing screw with finger.
3. Binocular or trinocular head:
Put the binocular or trinocular head onto the transmission adapter and tighten with the fixing
screw with finger.
and damp surrounding.
when it is not in use.
4. Eyepiece:
Insert eyepiece into the viewing tube.
5. Objective:
Make the mechanical stage down in order to install the objectives into the nosepiece from the
lowest magnification to the highest in the clockwise direction, please must be install them tightly
in place.
6. Condenser:
Make sure the oriented screw of the condenser holder is in the proper place.
7. Complementary color equipment:
Insert complementary color equipment into the proper place in need.
8. Filter:
It must be put on illuminator according to the user’s needs.
9. Attachable mechanical stage:
Put attachable mechanical stage on the rotatable mechanical stage.
10. Adjusting rod:
It is used to adjust center of the objective.

VI. OPERATION:
1. Illumination:
Turn on the power switch; adjust the brightness adjusting knob slowly to the desired level. In
commonly instance, don’t let it reach the lightest state, otherwise, that shorten the life of the bulb.
2. Focusing:
Begin observation of your specimen with the 4× Objective. Turn the coarse focusing knob until a
clear image is obtained, then use the fine focusing knob to enhance the observation of the
specimen to its clearest image. When the desired view is obtained under the lowest power (4×),
rotate the nosepiece to the next higher magnification (10×). The nosepiece should “click” into
position. You can obtain clear image with a little fine adjustment.
It is important to remember when adjusting the focus that the objective should never touch the
specimen. When increasing to 100× magnification, the objective will appear to be very close to
the slide. Because the 100× is an oil immersion objective, a drop of cedar-wood oil or other
immersion oil should be applied in the gap between the objective and the specimen. (Note: All
slides should be prepared with cover slips over the specimen for observation under the 100×
objective.) The 100 × oil immersion objectives should be wiped off with a piece of soft clean
cloth or lens tissue to remove the immersion oil immediately after using.
3. The center of objective superposition with the rotatable mechanical stage:
When the sample is clear enough, find a clear object and let
it coincide with the point of cross. Turning mechanical stage,
if axes of objective don’t coincide with the center of
mechanical stage, the point of object will circumrotate
around “S”. The track is circle, and adjust center of objective
to let “O1” move to “S” to see if they coincide or not. If not,
please adjust them.
4. Adjusting Abbe condenser:
1) The Abbe condenser can be moved up or down by
turning condenser focusing knob. When using high power objectives, better to making
the condenser up and whereas making the condenser down. Iris diaphragm should be
adjusted according to objective’s numerical aperture, in order to obtain better effect.
2) Take off the eyepiece to observe the center of aperture diaphragm on the condenser
overlay with center of objective's aperture. If both is away, may be adjusted the
condenser center adjusting screw until both is superposition.

5. Orthogonal polarized observation:
Because the polarizer is located in the light path, this time is single polarized light state after
focusing. Slide the analyzer into the light path, to adjust the analyzer adjusting rob on the
“0”position, also the polarizer is located on the“0”position, this time is orthogonal polarized light
state (polarized direction of the polarizer is at west-east, polarized direction of the analyzer is at
north-south).
When using 10×objective or lower. Please remove compensation lens, and adjust condenser to
proper place; when using 20 × objectives or higher, please push compensation lens to the previous
position and lift the condenser to the highest position.
Insert gypsum (λ), mica (1/4λ) sample, quartz wedge into complementary inlet according to your
need in order to test pixel.
6. Observation of cone light:
Observation of cone light is use 20× or higher objectives, push the Bertrand lens and
compensation lens into the light path, adjusting center of the Bertrand lens, to observe the cone
light characteristic of the sample.
VII. MAINTENANCE:
1. If there is any dirt settled on the lens, wipe it off gently with some lens paper. If alcohol is used, be
careful not to let it penetrate through the lenses and dissolve the gumming. Any dust settled on the
lenses can be blown away with an air blower or wiped off with a clean soft camel hair brush.
2. In cleaning mechanical parts and applying non-corrosive lubricant, take special care not to touch
the optical elements, especially the objective lenses.
3. Avoid high temperature.
4. Put objectives and eyepieces into box after using, and keep them in a cool, shady and dry place,
free from dust, fumes and moisture. If not stored in its box, cover with a hood to protect from
dust.
5. Like other optical instruments, the microscope should be kept out of direct sunlight in a cool, dry
place, free from dust, fumes and moisture. It should be stored in a case or covered with a hood to
protect it from dust.
6. The microscope has been carefully tested and inspected.
