Troubleshooting
This section provides many useful tips on how to solve common
problems while setting up or using the The Professor compound
microscope:
I can’t see an image. I only see a partial image.
• Check to see if you need new AA batteries.
• Check to see if the LED lights are turned on by pushing the
light button to the right or left on the base.
NOTE:
Switch the button right and the illuminator (lower) light will
turn on to view a standard microscope slide. Switch the button left
and the upper stage light will turn on to view macro (large) and
opaque specimens.
• Check to see if the objective lens is clicked into place.
• Turn the disc diaphragm, located underneath the stage, to
adjust the amount of light for viewing the specimen.
It is difficult to get the image in focus.
• Adjust the coarse focus knobs slowly.
• Check to see if there has been damage to the objective
lenses or eyepiece. If the lenses/eyepiece are dirty, use lens
paper and distilled water to rub gently to clean
NOTE:
Never rub the lenses/eyepiece when it is dry. This can cause
static charge that will attract dirt.
