BEFORE USE STM-3040
1．Notice
1. The microscope is composed of precision components ，Handle with care to prevent
abrupt.
2. 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 instrumnet .
3. Microscope should be place dry and clean place., Do not expose the microscope in the
sun directly ,Avoiding high temperature and violent vibration.
4. Handle stand with one hand and the base with another hand when moving microscope.。
5. If the bacterium solution or the water splash to the stage ,objective or viewing tube,pull
out the cord at once ,and wipe up the microscope .Othervise ,the instrumnet will be
damaged
6. The microscope illumination house will get hot when operating.。Make sure enough
room to disperse heat。
7. Connect with land to prevent lighting strake.。
8. Professional people to take the electronic conponents to prevent electricity strake
9. Use the factroy supplied power cord ,pleased
2．Maitenance
1. All lenses had been precisely adjusted and do not take the microscope apart.。
2. Do not take the Binocular head and focusing system apart 。
3. The instrument should be kept clean ,and prevent pollution while cleaning。
4. Wipe glass components softly , fingerprints and oil marked on it should be wipe off
with a tissue moistened with a small mount of xylene or a 3:7 mixture of alcohol and
ether
5. Never use the organic solution to clean the other surface, if necessary ,pleased choose
neutral detergent.。
6. Turn off electricity if microscope is moistured when operating .then wipe it off.。
7. Do not take any parts of microscope apart, or else effecting microscope function.。

3. Adjustment STM-3040
3.1 Binocular head
3.1.1 Interpupillary adjustment (fig.5)
Adjusting Interpupillary after observation
for another one using。Hold the two tubes,
①adjust interpupillary to obtain a clear
image.。
3.1.2 doipter adjustment(fig.6)
1．Turn the doipter adjusting rings ②to the zero
2．Set the sample on the stage。
3．Turn the zoom adjusting knob③to the 5X
position, focusing the sample。
4．Turn the zoom knob③to 0.8X position.
Observe though the left side eyepiece.
Adjusting the adoipter ring ②to focus
sample. 。then look though the right
eyepiece, adjusting the adoipter ring②to
focus sample.。
5．Repeat process3 and process 4 untill the image
was located on focus, the image also the
clear when change the magnification。
● working distance :115mm,set up the tray if
necessary 。
● operating ：take the lock-screw down by
screwdriver. Driver up the tray ⑤to a higher
lock-screw hole. Tighten it。

The function of microscope will no work efficiently for the unfamiliar using. Check the table
below if meet some troubles, then take proper action. Ask sales agent if the trouble will no be
tackled after check.。
Trouble Cause Remedy
1．Double images Interpupillary distance
is not correct
Readjust it
Diopter adjustment is
not correct
Readjust it
2．Dirt appears in the view
field
Dirt on the specimen Clean specimen
Dirt on the surfaces of
eyepieces
Clean eyepieces
3．Image is not clear Dirt on the surface of
objectives
Clear objectives
4．Image is not clear while
focusing change
Diopter adjustment is
not correct
Readjust diopter
Focusing is not correct Readjust it
5．The focusing knob is not
smooth
The focusing knob is
too tight
Loosen it to a suitable
position
6．The image is obscure
because of the head
slipping down during
observation
The focusing knob is to
o loosen
Tighten it to a suitable
position
