5. Image Capture
5.1 Installing
Connect the C-mount with CCD camera or connect camera with camera adapter, 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 is not clear.
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.

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
