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.
