Before Use BS-6012 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. Following

environment is required when operating: Indoor

temperature: 5℃～40℃, Max relative humidity: 80%.

(3) When moving the microscope, use one hand to hold its

arm①and the other hand to hold its front base②, and

lay it down carefully (See Fig. 1).

★It will damage the microscope by holding the stage,

focusing knob, head or light source when moving.

(4) When working, the surface of light source will be very

hot. Make sure there is enough room for the heat

dissipating around the light source.

(5) Connect the microscope to the ground to avoid

lightning strike.

(6) For safety, make sure the power switch③is at “O” (off)

and power it off before replacing the fuse (See Fig. 2).

(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 the power OFF devices have been set in the position

where is easy 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/ off the electrical device, please use these chemicals 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, power it off immediately and wipe it dry.
