voltage may cause short circuit and fire. The microscope will
be damaged.
Input voltage in the label: 220～240V 50/60Hz
Working voltage could be AC 220V, 230V or 240V
7. The bulb, fuse and electronic cord have been assembled already in the factory and please make sure to
use the spare parts of them supplied by the manufacturers. Improper bulb, fuse and electronic cord will
destroy microscope and cause fire. Please make sure to use PE electronic cord when using extra-long
electronic cord.
Spare bulbs: halogen bulb 12V20W (or 12V30W)
Spare fuse: 250V 1A delayed model, 5 × 20 minitype fuse
8. Never touch the surface of bulb with your hand directly. Please use gloves or cloth material when you
mount the bulb to avoid leaving fingerprints. Fingerprints or stains should be wiped off with a tissue
moistened with a small amount of alcohol. The fingerprints will etch on the bulb’s surface and make
brightness lower and life cycle shorter.
Please make sure the bulb’s touching points are Ok as it will not light or short circuit if the bulb’s touching
points are damaged. Insert the bulb’s legs into the bulb holder firmly. The bulb will go out if its legs have
not been inserted into the holder firmly. Such Operation may cause short circuit or smoking. At last, please
make sure if the collector has been mounted properly
9. Temperature for illumination
There will be high temperature when the bulb is lightened, never move the collector when the bulb is
lightened. Do not touch the bulb within 30 minutes after it has been gout out. Make sure the bulb has been
be cooling enough time (at least 30 minutes) to avoid scald.
Do not put fibre, papers and incendive things (eg. Gasoline, aether, methanol and ethanol) close to the bulb.
10. Make sure to turn off the power supply before assembling microscope, replacing bulb or fuse.
11. Using small amount of oil immersion is enough. The redundant oil will adhere to stage or condenser
and these will reduce microscope’s performance.
Get rid of the redundant oil or clean the lens by using aether or pure alcohol according to this instruction.
