5. MAINTENANCE & TROUBLESHOOTING
5.1 Maintenance
The stereo microscope is limited to the following maintenance only:
• Turn off the power switch after use, and put on the dustproof cover after the stereo microscope has cooled down.
• Do not operate the stereo microscope in a room with humidity higher than 75%.
• Remove dust or ordinary dirt on optical lens surfaces with a brush, rubber bulb blower and a moistened lens tissue.
• Use only optical lens tissues and optical lens cleaner (see below). Never clean a lens with a dry optical lens tissue.
Be sure to remove any dust before using lens tissue and cleaner.
• To remove stubborn oily or lipoid dirt (such as fingerprints), moist the lens tissue with a 3 to 7 ethanol-ether mixture
or a commercially available optical lens cleaning solution and then use it to wipe off the dirt.
• When cleaning an optical lens surface, wipe gently in a circle from the center to the edge.
5.2 Troubleshooting
Common fault Possible cause and remedy
Illuminator is not lit Check if the power switch is turned on.
Check the connection between the power cable and the power supply.
Check if the fuse has blown; if yes, replace with the spare fuse or contact
your local distributor.
Check if the illuminator is burnt out; if yes, replace the illuminator or contact
your local distributor.
Check if the supply voltage is the same as the working voltage of the instrument
(100~240VAC 50/60Hz).
If it’s not caused by any of the above causes, contact your local distributor.
Bulb flashes Loose contact of the illuminator plug socket. Connect the plug socket properly.
Fail to adjust focus
for specimen Check if the specimen is so big that the stereo microscope does not have enough
space to adjust the focus.
Check if the tension adjustment ring is so loose that the body slides down due to
its deadweight. Tighten the tension ring with the supplied hook wrench until the
body holds in place but will still move easily when the focus knobs are turned
Check if the eyepiece or objective lenses are dirty. If yes, wipe the lens according
to the instructions in section 3.2 of Operation of the stereo microscopes.
