Working principles of the video microscope system

A clear picture of tiny object could be seen through the Microscope,

then, such picture would be grabbed and tu rned into video signal by the
CCD camera, and then, the video signal would turn into a digital picture
on the LCD display, meanwhile, the video signal will be transformed in
the signal transition box and then sent via the USD2.0 access to the
computer for display, picture-grapping, photographing, measuring,
saving and printing as well. Users can get the picture of ideal video
effect by turning the zooming ring of the lens section.

suitable zooming times.

3) Adjust the lightness: lightness plays an important role in imaging,

weak lightness makes the image dim and not clear while strong
lightness changes the original colors of the object’s image. The more
spectrums, the more vivid the imaging will be. Moreover, refraction
of the light also affects the imaging quality. So the illumination and
lightness have to be carefully chosen and adjusted.

Dysfunctions diagnosis

1. Vague image:

Generally results from the improperly adjusted working distance,
please re-check and make sure the working distance is approx 95mm
as required.

Generally results from strong lightness/brightness, please adjust
lightness/brightness to a properly extent.

4. Image with white spot:
Generally results from refraction of the light or strong

lightness/brightness, please adjust the light incidence and the
lightness/brightness to a properly extent. Normally, scattering light is
a better mean of illumination.

5. No image appears on the display screen:
This may result from many factors, among which the most common

two are display screen dysfunction and signal dysfunction. When this
happens, first, check whether the power supply system is properly
working or not; open the top cover of the machine, if the indicator of
CCD camera is on, it means the power supply system is all right, then
the below procedures should be followed:
(1) Display screen dysfunction: Normally, if the display screen is OK,

press button ①, the caught image or the two-second “no signal”

-14­indication should be on the screen, otherwise display screen

dysfunctions can be deemed affirmative. This symptom can also
be judged from the exterior display connected via the AV OUT
outlet.

(2) No signal dysfunction: When no signals are sent to the display, the

backlight of the display screen will be off even it is power on, so

2. Image is dim, unclear, colorless, red, and with “snow stains”:
Generally results from weak lightness/brightness, please adjust
lightness/brightness properly strong.

3. Image is too white:

15

no image appears on the screen. When this happens, please check
the pass through which the signals are transmitted. Normally, the
ocular microscope is deeded to be ok without outside force, and if

the video signal transmitting wire is ok, then CCD camera will be

16

considered to arise.

Attention:

① If any dysfunction happens to CCD camera or display screen,

please contact the supplier for repair.

② Please take care of the power supply voltage, wire polarity and the

video format, if users want to change the CCD camera by
themselves.

6. No image appears on computer
When the screen of PCE-VM 21/22/23oes well, but no image

appears on computer, please check whether the computer works well
or whether the system of the machine and the computer is properly
connected or not, if affirmative answer comes, then the display card
dysfunction is deemed to arise. When this happens, please open the
top cover of the machine and check whether the indicator of the
display card is on or not, and check if the connections between the
card and the signal outlet as well as the video signal input are ok, if
yes, then the display card dysfunction is confirmed to arise. Please
contact the supplier for repair.

Note: High voltage inside, take care, please make sure the

Electricity is cut off when checking.

The display is vulnerable and may be damaged forever

should its interior parts are changed by any means, to avoid

which please let a qualified person to disassemble and fix the

machine when faults and dysfunctions happen.
