Before Use MT-50 Series
1. Operation Notice
1. As the microscope is a high precision
instrument, always operate it with care, and
avoid physical shake during the operation.
2. Do not expose the microscope in the sun
directly, either not in the high temperature, damp,
dust or acute shake. Make sure the worktable is
flat and horizontal.
3. When moving the microscope, use both hands
to hold its back hand-clasping ① and the front
base ②, and lay it down carefully (see Fig. 1).
★ It will damage the microscope by holding
the stage, focusing knob or head when
moving.
4. When working, the surface of condenser will
be very hot. Make sure there is enough room for
the heat dissipating around the condenser③ (see
Fig. 2).
5. Connect the microscope to the ground to avoid
lightning strike.
6. For safety, make sure the power switch ④ is
at “0” (off) and power it off before replacing the
bulb or fuse, and wait until the lamp cools down
(see Fig. 3).
★ Bulb selected only: 3.3V 3W LED （class
3B）light 6V 30W HAL.
7. Wide voltage range is supported as 100~240V.
Additional transformer is not necessary. Make
sure the voltage is in this range.
8. Use the special wire supplied by our company.
9. All power OFF devices have not been set in the
position where is difficult to operate.

2. Maintenance
1. Wipe the lens gently with a soft tissue. Carefully wipe off the oil marks and fingerprints
on the lens surfaces with a tissue moistened with a small amount of 3:7 mixture of alcohol and
ether or dimethylbenzene.
★ As the alcohol and ether is flammable, don‟t place these chemical near to fire or fire
source. For example, when turning on or turning off the electrical device, please use these
chemical in a ventilated place.
2. Don’t use organic solution to wipe the surfaces of the other components. Please use the
neutral detergent if necessary.
3. If the microscope is damped by liquid when using, please power it off immediately and
wipe it dry.
4. Never disassemble the microscope, otherwise the performance will be affected or the
instrument will be damaged.
5. After using, cover the microscope with a dust cover.
