5. Image Collection
5.1 Installing
Connect the C-mount with CCD camera or connect camera with camera adaptor, then connect it with
c-mount, finally put it into microscope.
5.2 Using
First get a clear image from eyepiece, then put out lever on the side of trinocular head, and collect
image with camera. Clear image should be in screen.Adjust B14 fine focusing knobs to get it clear if
image isn’t clear.
5) Adjust condenser aperture
diaphragm Adjust condenser ⑤(condenser focusing
screw M) and aperture (Aperture diaphragm
lever D)
Observing
1) Turn power switch,
adjust light
Turn on Switch L, and turn Potentiometer K.
2) Put the sample Put the sample on stage ④, (open the clamp
C, and put the sample into it), turn stage knob
H to put the sample into optical path.
3) Put 10X objective into
optical path and focus
Turn Nosepiece B, put 10×objective into
optical path. Turn Coarse & Fine Focusing
Knobs I and N to focus.
4) Adjust interpupillary
distance and diopter
Adjust head ⑧to make two fields into one;
adjust diopter adjuster A to make diopter for
two eyes same.
6) Adjust and center field
diaphragm Adjust field diaphragm
(field diaphragm ring E)
Put the objective into
light path, and focus

6. Maintenance
6.1 Clean microscope
6.1.1 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).
6.1.2 Alcohol and ether all are burnt early, please take them away from fire. Be careful for turn on
and off power.
6.1.3 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.
6.1.4 Plastic should be cleaned by soft cloth with clear water.
6.2 Environment of using and placing
6.2.1 Microscope should be used and placed in a cool, dry, non-dust, non-shake and non-corrosive
gases environment.
6.2.2 Microscope should be used in environment of indoor temperature 0°-40°C and maximum
relative humidity 85%.
6.2.3 Removing equipment is suggested to be installed when microscope used in heavy humidity
area to avoid fungus and mist damage instrument.
6.2.4 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.
6.3 Replacement of bulb
6.3.1 Turn off power, and pull out plug.
6.3.2 Wait the bulb become cool.
▲Please be sure that the bulb is cool, then follow
by the nest operations.
6.3.3 Lay aside the microscope reliably, unscrew the
knurled thumb screw of the lamp housing cover on
the underside of base.
6.3.4 Pull over the lamp housing cover.
6.3.5 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.
6.3.6 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.
6.4 Replacement of fuse
6.4.1 Cut off power of microscope, and pull out the
plug.
6.4.2 Unscrew fuse cap in the back of base, take out
old fuse.
6.4.3 Replace a new fuse, then screw the fuse cap.

7. Trouble shooting
In the period of using this series microscope, if there is any trouble occurs, please referring to the
following sheet listed some common troubleshooting resolve them.
Trouble Causation Remedy
Switch on but bulb dark
Plug is unreliable Plug in again
Bulb is broken Change bulb
Fuse is broken Change fuse
Bulb is flickering or
brightness is
unsteady
Bulb is unstable Insert it again
Bulb is broken Replacing bulb
Brightness of view field
isn’t enough or is
Uneven
Bulb specification doesn’t
meet the requirement Replacing bulb
Brightness isn’t adjusted
correctly Adjust rotation potentiometer
Objective isn’t in correct
position Make the objective in correct position
The size of iris aperture is too
small Adjust the size of iris aperture
Brightness of view field
isn’t enough or is
Uneven
Lens (objective,eyepiece,
condenser, light collector) has
dust Clean it
Position of condenser is too low Higher condenser
Image isn’t clear
(contrast or definition
isn’t enough)
Cover glass of specimen
doesn’t meet the
requirement
Use required thickness cover
glass (0.17mm)
Cover glass of specimen isn’t in
up direction Place specimen correctly
Surface of objective lens
isdirty (especially it is easy for
the front lens of 40X objective
to dip in immersion oil)
Clean it
Immersion oil isn’t used for
100X objective (oil) Use immersion oil
Immersion oil doesn’t meet the
requirement Use immersion oil supplied by us
There is bubble in immersion oil Clear the bubble way
Size of iris aperture isn’t
proper Adjust the size of iris aperture
Position of condenser is too low Readjust the position of
condenser
One side of image is
dark or image is
moving as focusing
Objective isn’t in correct
position Make the objective in correct position
Specimen isn’t placed correctly Place specimen levelly on
stage
and clip it with clamp
Objective touches
specimen as changing
low times objective to
high times objective
Cover glass of specimen isn’t in
up direction Place specimen correctly
Cover glass doesn’t meet the
requirement Use required thickness cover glass (0.17mm)
Image observed by two
eyes aren’t in
superposition entirely.
Interpupilary distance isn’t
adjusted correctly Adjust interpupilary distance according to two eyes
