Working Environment
2.1 Temperature range is 0℃～40℃and the max. humidity is 85%
2.2 Altitude :<2000m
2.3 Barometric：86KPa～106KPa
2.4 Avoid high temperature and humidification otherwise there will be fog or mold on
the lens
2.5 Keep the environment breezy and cover the microscope with the dust-cover
2.6 Avoid violent vibration as the vibration will reduce the image’s quality
3. Focusing knob
Never turn the left and right focusing knob in the
adverse direction at the same time. Do not turn the
coarse focusing knob when the stage reaches max.
position. These improper operations will make
focusing structure unworkable.
4. Clamp

6. Use the space parts supplied by the manufactures
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 12V 20W, 12V50W（reflect）
LED lamp 5W(transmission), 10W（reflect）
Spare fuse: 250V 1A delayed model, 5 × 20 minitype fuse
7. Mounting the bulb
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
8. 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.
9.Make sure to turn off the power supply before assembling microscope,
replacing bulb or fuse.
