Adjusting Focusing Tension
1.
To adjust the tension of the focusing knobs, first locate the black ridged tension knob on the inside of the coarse
focusing knob.
2.
To decrease tension, rotate the adjustment forward, towards the stage (counterclockwise). To increase, rotate
away from the stage (clockwise).
Note: If your stage is slipping down after setting the focus, you need to increase the tension.
Changing the Bulb
1.
Before changing the light bulb, first pull the plug out of the electrical socket and wait for the lamp to cool down.
The light can get hot when a halogen system is in use, so please be careful to avoid being burned.
2.
There is a door on the front of the microscope near the base lens that slides forward. Remove to access the bulb
on the unit.
3.
Reinstall the door prior to use to avoid hurting your eyes with the brightness of the bulb’s illumination.
Maintenance/Precautions
-
All glass surfaces must be kept clean. Fine dust on the optical surface should be blown off using a hand blower or
gently wiped off with a soft lens paper tissue/nonabrasive lint free cloth.
-
Carefully wipe off oil or fingerprints on the lens surfaces using tissue moistened with a small amount of lens
cleaner (we recommend Sparkle brand optical cleaner).
-
Do not use Sparkle to clean other elements of the microscope. Use a neutral detergent on any plastic or painted
surfaces.
-
Do not assemble or disassemble the microscope’s electrical components yourself without advisement from one of
our technicians. Doing so will void your warranty unless by advisement of one of our technicians to do so.
-
After use, cover the microscope with the provided dust cover.
-
Keep your AmScope microscope in a dry, clean location in order to prevent rust or other damages.
