Before Use BS-3080

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, horizontal and

firm enough.

Following environment is required when operating:

Indoor temperature: 5℃～40℃, Max relative humidity:

80%.

3. When moving the microscope, use both hands to

hold the position① and ② of the microscope. (See

Fig. 1)

★It will damage the microscope by holding the

observation head, focusing knob, body or objectives

when moving.

4. External power adapter is used. Wide voltage range

is supported as 100~240V AC.

5. Use the special wire supplied by our company.

2. Maintenance

1. Keep all the surface of the lens clean. Wipe the lens gently with a soft lens tissue or blow

away the dust. Carefully wipe off oil or fingerprints on the lens surfaces with tissue

moistened with a little of 3:7 mixture of alcohol and ether.

2. Do not use organic solution to wipe the surface of other components, especially the surface

of plastic components. Please use the neutral detergent if necessary.

3. Never disassemble the microscope yourself, otherwise it will influence its function or

damage it.

4. After using, cover the microscope with a dust cover to prevent it from the dust, and store it

in a place free from moisture to avoid rusting.

5. To keep the performance of the microscope, please check it periodically. For more details,

please contact the agents nearby.

2-2 Assembling Steps

2-2-1 Assemble the Focusing Bracket Group

Loosen the lock knob① of the focusing bracket group,

insert the hole② of focusing bracket group into the

column③, until the focusing bracket group to the

lowest position. Then tighten the lock knob① to

prevent the microscope from turning.

◎Slowly insert it, do not force too much.

◎To avoid the microscope turnover, the focusing

bracket group must assemble on the same side to the

worktable of base group, as the left view of Fig. 3. If

assemble the focusing bracket group on the wrong side,

the microscope will turn over as the right view of Fig. 3.

2-2-2 Assemble the Microscope Body

1) Remove the decorative cover① of the focus bracket

group, and loosen the M4 inner hexagon screw with a

M4 inner hexagon spanner. (See Fig. 4)

2) Match the dovetail interface③ of the microscope

body with the dovetail groove② of the focus bracket

group, and insert it from top to bottom as the direction

shown in the figure.

3) Tighten the M4 inner hexagon screw on the focus

bracket group with a M4 inner hexagon spanner, then

put the decorative cover① back.

2-2-3 Assemble the Objective

1) Rotate the objective as the arrowhead direction

shown in the figure, and screw the objective② into the

objective installation screw hole①. (See Fig. 5)

2-2-4 Assemble the Head

1) Loosen the head lock-screw① fully with a M4 inner

hexagon spanner.

2) Make the two tubes face forward, from a little rear

position of the center, insert the coattail interface on

the bottom of head into the hole of body with a little

rear inclined. Match the orientation groove② of the

head with the orientation pin③ of the body, and then

screw down the lock screw①. (See Fig. 6)

2-2-5 Assemble the Eyepiece

1) Take down the eyepiece tube cover①.

2) Insert the eyepiece③ into the eyepiece tube, until it

touches the bottom. Lock the eyepiece by the

lock-screw② (See Fig. 7)

◎Install or Remove the Reticle

1) Unscrew the pressure ring from eyepiece (see Fig. 8).

2) Clean the reticle, then install it into the pressure ring

with the scaled surface upward (see Fig. 8).

3) Screw the pressure ring which is with reticle into the

eyepiece until tight enough.

4) To remove the reticle, first unscrew the pressure ring

from eyepiece, then take down the reticle and keep it

with clean paper packed.

2-2-6 Assemble (Remove) the Worktable

1) Place the worktable on the installation hole of the

base.

2) To remove the worktable, use fingertip to press down

the worktable nearby the pillar edge (as the arrowhead

direction shown in Fig. 9), then the other end of

worktable will turn up. (See Fig. 9)

2-2-7 Assemble the Clip

1) Use the clip to avoid the specimen moving.

2) Insert the clip① into the two holes of the base, as

the arrowhead direction shown in the figure. (See Fig.

10)

2-2-8 Fix the Microscope Body Position

1) Loosen the lock knob①, and rotate the microscope

body and the focusing bracket group left and right.

2) Match the center of zoom body group with the center

of worktable, then lock the lock knob①. (See Fig. 11)

2-2-9 Connect the LED Light Source and Power Cord

1) Make sure the main switch is at “O” (OFF)

position.(See Fig. 12)

2) Insert one end of the optical fiber① into the inner

hole② of the power supply box to the bottom, and

align the flat surface with the lock screw③, then lock it

with the lock screw③.

3) Insert the other end of the optical fiber① into the

hole of the base④, then lock it with the lock screw.

4) Insert one end of the power adapter⑥ into the inner

hole⑤ of the power supply box.

5) Insert one end of the power cable⑦ into the

corresponding hole of the power adapter⑥, and the

other end into the power supply socket.

★The power supply box supports wide voltage as

100-240V.

★Don’t use strong force when the power cord is

bended or twisted, otherwise it will be damaged.

★Use the special wire supplied by our company. If it’s

lost or damaged, choose one with the same

specifications.

★Connect the power cord appropriately to make sure

the instrument is connected to ground.

3. How to Use BS-3080

3-1 Set Illumination

1) Put through the power and turn on the main

power switch to“ON”.

2) Adjust the light adjustment knob② until the

illumination is comfortable for observation. Rotate

the light adjustment knob clockwise to raise the

brightness. Rotate the light adjustment knob

counterclockwise to lower the brightness(See Fig.

13).

3-2 Adjust the Reflector

◎The reflector has two surfaces, one is plane mirror,

the other is sandblasted aluminum. Both surfaces can

reflect the light, but the reflection of plane mirror is

stronger.

1) Adjusting the adjustment knob① of the

reflector(See Fig. 14), can change the reflector

surface, also can change the lighting range after

reflected.

2) The adjustment knob① of the reflector can be

moved front and rear according to the arrowhead

direction, to achieve different lighting effects.

3-3 Adjust the Focusing Tension

1) If the handle is very heavy when coarse focusing,

or the specimen leaves the focus plane soon after

focusing, or the stage declines itself, these problems

can be solved by adjusting the tension adjustment

ring①.(See Fig.15)

2) Rotate the tension adjustment ring① according to

the arrow direction in the figure, to tighten the

focusing system; rotate the tension adjustment

ring① in the opposite direction, to loosen the

focusing system.

3-4 Adjust the Diopter and Focus

★Before operating, make sure the eyepiece lock

screw is tighten.

1) Rotate the zoom knob to the maximum

magnification. (See Fig. 15)

2) Rotate the focusing knob if the image is unclear

when observed with the right eyepiece.

3) Rotate the zoom knob to the minimum

magnification.

4) Rotate the diopter adjustment ring of right

eyepiece if the image is unclear when observed with

the right eyepiece. (See Fig. 16)

5) Then rotate the zoom knob to the maximum

magnification, if the image is not clear enough when

observed with the right eyepiece, repeat Step (3)~(5)

as above.

6) Then rotate the zoom knob to the minimum

magnification, turn the diopter adjustment ring of left

eyepiece if the image is not clear enough when

observed with the left eyepiece. (See Fig. 16)

3-5 Adjust the Interpupillary Distance

Hold the left and right prism boxes and rotate them

according to the arrowhead pointed in Fig. 17, until

it’s comfortable to view.

Adjustable range: 50~76mm.

3-6 Adjust the Elevation Angle of Observation Head

1) Adjust the height and elevation of observation

tube to the most comfortable position for

observation.

2) Use both hands to hold the binocular components,

to move it up or down to the position required. (See

Fig. 18)
