Before use SZG series
Operation
1. As the microscope is precision instruments, it should be taken carefully and avoid impact during
transportation.
2. The microscope should be set in dry and clean place. Do not expose in the sun directly and avoid high
temperature and violent vibration. The environment temperature should be 0 ℃～40 ℃and the humidity
should be 85%.
3. To keep the image clearly, do not leave finger prints or stains on lens.
4. Make sure the main power supply is suitable within 90-240V before use.
5. Do not adjust the right and left focusing knob to opposite direction simultaneity, otherwise it will with
trouble.
6. Please shut off power supply before replace bulb.
7. Please shut off power supply before remove the microscope.
8. Please holder the microscope from arm and base and put off safety.
★If hold on the stage, focusing knobs or observation tubes during removing, it will damage the
microscope.
Maintenance
1. All lenses should be kept cleanly. Use air or lens cloth to clear dust; Use cotton pledget with 3:7 ethanol
and aether mixed to clear spot and fingerprint.
2. Never use organic solution to clean the surface of microscope, especially the plastic parts. If necessary,
please choose neutral detergent.
3. Do not disassemble or assemble the microscope yourself to avoid damaging the capability.
4. After using, put on dust cover to protect microscope and put in dry place to prevent rust.

5. Troubleshooting SZG series
The performance of the microscope can’t be made fully because of unfamiliar using, this table will give some
advices:
Trouble Cause Remedy
1. Optical parts
⑴Brightness too bright or
too dark
Adjustment of brightness is not
correctly Adjust it correctly
Dirt on specimen Clean specimen
Dirt on surface of eyepiece Clean eyepiece
Dirt on surface of objective Clean objective
⑵Dirt appears inside of
view field
Dirt on stage Clean stage
Interpupillary is not right Re-adjust the interpupillary
Diopter is not right Re-adjust the diopter
⑶Double image
Different magnification of both
eyepiece Use the same eyepiece
⑷Image is not clear Dirt on surface of objective Clean objective
Diopter is not right Re-adjust the diopter
⑸Image blur during
focusing Wrong focusing Focus again
⑹Incision image appears
when observe through
eyepiece or TV device
Light path selection lever is not
at right position Turn it to right position
⑺Image is not clear on
monitor during focusing
Wrong focus depth of video
device
Re-adjust the focus depth by adjusting
ring on TV adapter
2. Electrical parts
Wrong setting of bulb Set the bulb correctly
Bulb has burned out Replace the bulb
Fuse has burned out Replace the fuse
⑴Bulb does not work
Dirt on the stage stopped the
light path Clean the stage
⑵Bulb burned out The bulb is not standard Use standard bulb
Bulb is going to burn out Replace the bulb
⑶Light flickered out
The wires do not connect right Connect it correctly
3. Focusing parts
⑴Focusing knobs work
stiff Too tight of the focusing knobs Loose it to suitable
⑵Image is not clear by
the focusing arm slipping
down during focusing
To loose of the focusing knobs Tight it to suitable
