Troubleshooting
This section provides many useful tips on how to solve common
problems while setting up or using the Comprehensive Scope 2:
I can’t see an image. I only see a partial image.
•
Check to see if the power supply is plugged into an
electrical outlet or the battery is charged if using
cordless.
•
Check to see if the LED lights are turned on by switching
the power button on the back of the microscope. A red
indicator light should glow if the LED lights are on.
•
Check to see if the objective lens is clicked into place.
•
Adjust the disc/iris diaphragm, located underneath the
stage, to control the amount of light illuminating the
prepared slide.
•
Check to see if the dimmer switch (rheostat) is turned
clockwise to allow the intensity of light to increase.
It is difficult to get an image to focus.
•
Adjust the coarse focus knobs slowly.
•
Check to see if the objective lens is clicked into place.
•
Check to see if there has been damage to the objective
lenses and eyepiece(s). If the lens/eyepiece is dirty, use
lens paper and distilled water to rub gently clean.
NOTE:
Never rub the lens/eyepiece when it’s dry. This can cause static
charge that will attract dirt.
