Before Use BS-2043 Series

1. Operation Notice

1. As the microscope is a high precision

instrument, always operate it with care, and avoid

physical vibrations.

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, keep holding the

rear cover hand clasp①and the front end of

microscope body②with each hand. Handle with

care. (See Fig. 1)

★It will damage the microscope by holding the

stage, focusing knob or head when moving.

4. Connect the microscope to the ground to avoid

lightning strike.

5. For safety, make sure the power switch ③is at

“O” (off) and power it off before replacing the

bulb, and wait until the bulb and base cool down

completely (see Fig. 2).

★Bulb selected only: single 3W LED

6. Wide voltage range is supported as 100~240V.

Additional transformer is not necessary. Make

sure the power supply voltage is in this range.

7. Use the special power adapter 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 chemicals near to fire or fire

source. For example, when turning on or turning 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, 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.

2-2 Assembling Steps

2-2-1 Assemble the Condenser

1. Rotate the coarse focusing knob①according

to the direction shown in the figure, to raise the

stage to the highest position (see Fig.3).

2. Fully loosen the condenser lock-screw②.

3. Insert the condenser into the hole of base

according to the arrowhead pointed, until the

condenser is aligned with the base, and rotate the

condenser to make the handle face forward.

4. Tighten the condenser lock-screw②of

condenser, then raise the condenser with the

up-down knob to the highest position.

2-2-2 Assemble the Objective

1. Rotate the coarse focusing knob①to lower

the stage to a suitable position (see Fig. 4).

2. Then install the objectives into the

nosepiece②from the lowest magnification to

the highest in clockwisedirection.

★When operating, first use the low

magnification objective (4X or 10X) to search for

specimen and focus, and then replace with high

magnification objective to observe.

★When replacing the objective, rotate the

objective nosepiece until it sounds “ka-da”, to

make sure the objective wanted is in the center

of optical path.

2-2-3 Assemble the Eyepiece

1. Take down the cover of eyepiece tube①.

2. Insert the eyepiece② into the eyepiece tube,

until it touches the surface.

3. Tighten eyepiece with M2.5 inner hexagon

lock-screw③(see Fig.5).

3. Operations BS-2043 Series

3-1 Set Illumination

1. Put through the power and turn on the main

power switch to “—”(turn on) on the side.

2. Adjust the light adjustment knob②until the

illumination is comfortable for observation.

Rotate the light adjustment knob in clockwise to

raise the voltage and brightness. Rotate the light

adjustment knob in counterclockwise to lower the

voltage and brightness (see Fig.7).

3-2 Place the Specimen Slide

1. Push the wrench①of the specimen holder

backwards.

2. Place the cover glass of slide②faced upwards

into the clip, loosen the wrench①and clamp the

slide (see Fig. 8).

3. Rotate the X and Y-axis knob③of the stage,

and move the specimen to the center (aligned

with the center of objective).

3-3 Adjust the Focus

1.Rotate the condenser up-down knob①

according to the direction shown in the figure, to

raise it to the highest position.

2. Move the objective 4X into the optical path.

3. Observe the right eyepiece with right eye,

rotate the coarse focusing knob②until the

specimen outline appears in the view field (see

Fig. 9).

4. Rotate the fine focusing knob③ for clear

details.

★The position screw ④can avoid the

objective touching the clips.
