3.Installation & Operation

3.1 Installation

1) Put out the main body, loose the body fixed screw.

2) Put out the reflection illumination unit and halogen lamp house, then fix the lamp house into the back of

reflection illumination unit by the lamp house fixed screw. Insert the power wire of the lamp house into the

power output socket of power house. Fix the reflection illumination unit to the main body, and tighten the

body fixed screw.

3) Put out diaphragm slide and polarizer slide. Put down a handle of diaphragm slide, and insert it into the

groove of the back of the reflection illumination, put up the handle. Put on the polarizer slide as the same

(position groove face to front and insert into reflection illumination)

4) Put out binocular head (trinocular head), fix it onto the reflection illumination, and tighten the eyepiece

tube fixed screw.

5) Put out the dust cover of the eyepiece tube, and insert eyepiece into the tubes.

6) Take out the objective from the packing box, and drive them into the holes of nosepiece orderly and

tightly according to the times.

7) If it is transmitting and reflection microscope, please put out condenser, and put it on the condenser

holder.

8) Put the glass plate stand on the stage, and fix it by the fixed screw, and place the glass plate to the stand.

3.2 Operation

Confirm the voltage is available, then take power

1) Turn potentiometer, and make the light to the lowest position. Open the power switch, and adjust the

potentiometer to get the available light. If reflection observing, operate the potentiometer and power

switch in the power house; if transmitting observing, operate the potentiometer and power switch in the

microscope main body.

2) Sample placing

Choose an available stage plate, put the sample onto it, turn the stage knob to put the sample into the

light path. If reflection observing, stage plate and glass plate should be chosen; if transmitting

observing, glass plate and clamp should be chosen.

3) Put 10X objective into light path, turn coarse focusing knob, observe from right eyepiece with right

eye, then turn slowly fine focusing knob to make the image clear after finding image.

4) Interpupillary distance adjustment

Interpupillary distance is different for everyone, so interpupillary distance should be adjusted before

using binocular microscope. Please take the two eyepiece tubes to turn until the bright rings observed

by two eyes are in superposition entirely.

5) Diopter adjustment

As focusing for binocular, user should observe right eyepiece with right eye, and make the right eyepiece

clear by focusing adjustment, then observe the left eyepiece, at the same time, adjust the diopter ring of the

left eyepiece tube to make the image of left eyepiece clear as same as the right eyepiece.

6) Field diaphragm adjustment

a. If reflection observing, the field diaphragm has been adjusted well in factory, and user doesn’t need to

adjust. Using field diaphragm lever to adjust it.

b. If transmitting observing, turn the field diaphragm ring to make the diaphragm smaller than the field of

eyepiece, the image of field diaphragm can be gotten in field. Adjust the centering adjust screw to make the

center of field diaphragm overlap with the center of eyepiece field. Make the image of field diaphragm

smaller than eyepiece field to adjust again. Larger the field diaphragm to make it disappeared.

7) Aperture diaphragm adjustment

a. If reflection observing, pull the diaphragm slide handle to choose the available diaphragm.

b. If transmitting observing, adjust the condenser aperture diaphragm lever to change the size of aperture

diaphragm to change the contrast of the image.

8) Polarizer unit using:

Polarizer and analyzer should be used together when polarizing observing. Put the polarizer slide into

optical path, then insert the analyzer slide into the groove of the reflection illumination unit, turn

slowly the lever of analyzer slide to polarizing observing.

9) Stage coarse range using:

When the size of sample is too large to adjust the coarse knob availably, hold the stage by hand and loose

the stage up-down adjusting screw to adjust the position of stage. Tighten the stage up-down adjusting

screw after get the available position.

10) Usage of 100X immersion oil objective

Adding moderate immersion oil between the front lens of 100X objective and the cover glass of specimen

can make the image clearer. Please pay attention that air bubble and impurity can’t be in the immersion oil,

otherwise, the image would be affected.

First of all, take 40X objective which has been focused well out from bright path, then take 100X objective

into bright path. At this time, nosepiece or stage moving knob should be turned slightly, and also slightly

turn fine focusing knob to clear away the air bubble of immersion oil, otherwise, the air bubble would

affect the image badly.

▲ After immersion oil used, the oil of specimen and the microscope surface should be soon cleaned by

absorbent cotton, lens paper, gauze or soft cotton cloth with moderate mixture of pure industrial

alcohol and ether (proportion 1:4).

4. Maintenance

4.1 Clean microscope

4.1.1 Don’t touch the lens with hand, Dust on lens should be cleaned by soft brush or absorbent cotton or

cleaned by absorbent cotton, lens paper with the mixture of alcohol and ether (proportion 1:4).

4.1.2 Alcohol and ether all are burnt early, please take them away from fire. Be careful for turn on and off

power.

4.1.3 Don’t clean painted metal and galvanizing metal with organic solvent such as alcohol, ether or the

mixture of the both. Silicon cloth or soft cleaning preparation is suggested to clean it.

4.1.4 Plastic should be cleaned by soft cloth with clear water.

4.2 Environment of usage and storage

4.2.1 Microscope should be used and placed in a cool, dry, non-dust, non-shake and non-corrosive gases

environment.

4.2.2 Microscope should be used in environment of indoor temperature 0°- 40°C and maximum relative

humidity 85%.

4.2.3 Removing equipment is suggested to be installed when microscope used in heavy humidity area to

avoid fungus and mist damage instrument.

4.2.4 Please pay attention to prevent microscope from violent shake and vibration in application and in

carrying. Don’t drag it on the surface of worktable to avoid damage to microscope and worktable.

4.3 Replacement of bulb

4.3.1 Turn off power, and pull out plug.

4.3.2 Wait the bulb become cool.

▲ Please be sure that the bulb is cool, then follow by the nest operations.

▲ Only use 6V20W or 12V50W halogen lamp bulb.

4.3.3 Lay aside the microscope reliably, unscrew the knurled thumb screw of the lamp housing cover on the

underside of base.

4.3.4 Pull over the lamp housing cover.

4.3.5 Pull out the bulb should be replaced, hold a new bulb with silk cloth to avoid fingerprint and dust

affect bulb brightness and service life, and insert fully the contact pins into the bulb socket.

4.3.6 Close the lamp housing cover, and screw the knurled thumb screw.

▲After working for above 10 hours continuously, better cut off the microscope about 30 minutes.

4.4 Replacement of fuse

4.4.1 Cut off power of microscope, and pull out the plug.

4.4.2 Unscrew fuse cap in the back of base, take out old fuse.

4.4.3 Replace a new fuse, then screw the fuse cap.
