Installation of the USB2.0 access driver and the operation processes
:
For installation steps, please refer to “Installation manual of the USB2.0
access driver”.
Errors and dysfunctions diagnosis/analysis:
1. Vague image:
Generally results from the improperly adjusted working distance or the
lens focus, please re-check and make sure the working distance is approx
30mm as required.
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:
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 beam from the tested object,
please adjust the light incidence and the lightness/brightness to a properly
extent. Normally, scattering light is a better mean of illumination.
5. Malfunction of rotating watching device
The rotating watching device is drived by micro-motor. Normally if it is
not working that is not rotating. The reason may be mechanical error or
electrical failure.
When the watching device is not rotating, please check it carefully and
find the reason. Observation: Incline the unit, watch the small gear of
micro-motor is turning, if it is turning, mean the gear coupling between
small gear and big gear is too loosen. Listening: if you can hear some noise
from the inside of micro-motor, it mean the gear coupling between small
gear and big gear is too tight. The mechanical part after transportation or
long time using, it may cause the gear coupling is too tight or loosen. when it
happens, need to loosen the adjusting screws of gear coupling, then switch
on motor, let the watching device rotating, then tight the four screws. If it
still not works, please check electrical parts.
The motor work at 12V DC,power supply from the bottom base, when
motor not working, first check if the power supply to motor is normal or
not,then check the power cable and socket. Usually there is little possibility
