Before Use BS-2082 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 both hands to

hold its back hand-clasping ① and the front base ②,

and lay it down carefully (see Fig. left).

★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 switch is at “O”

(off) and power it off before replacing the bulb or

fuse (see Fig. left).

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.

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, 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.

3. Safety Sign

2-2 Assembling Steps

2-2-1 Assemble and Replace the Halogen Bulb

(1) Loose lock-screw ① completely by M4 spanner,

then take off the cover group. (See Fig. 1)

(2) Open the bulb lock piece②, and take the bulb③

with clean glove or soft tissue, insert the bulb pins④

into the jack on the bulb holder⑤, the bulb should be

install the cover group.

★Don’t touch the bulb with fingers. If there is a

fingerprint left on the bulb, please wipe it with

clean soft cloth.

★Bulb selected only: 12V/100W Halogen bulb (Philips

7724).

★Before replacing the bulb, make sure to cut off the

main power and wait for both the bulb base and

bulb cooling down.

2-2-2 Assemble the Light Source Group

Push the light source holder① into the body holder,

Make the light source group to be horizontal with the

body group and lock the screw②. (See Fig. 3)

2-2-3 Assemble the Stage

(1) Loosen the lock-screw① on the stage. (See Fig. 4)

(2) From a rear area of the rounded hole center on the

base, carefully ring the two “V” buttons on the bottom

of the stage into the “V” rounded groove②, then

screw down the lock screw①.
