BEFORE USE BS-3030

Operation

1) As microscope is a precision instrument, handle with care, avoiding impact or

abrupt movement during transportation.

2) Microscope ought to be placed in a dry and clean place. Do not expose the

microscope in the sun directly. Avoid high temperature and violent vibration.

Usually, following environment is required indoor temperature: 0°C - 40 °C, Max.

relative humidity:85%.

3) To keep the image clear, do not leave fingerprints or stains on the surfaces of

the lens.

4) Before use, please check the power supply in compliance with the microscope

power required.

5) Never turn the left and right focusing knob in the adverse direction at the same

time, otherwise the microscope will be damaged.

6) When use photo set to capture image, please ensure the stability of microscope,

make sure the main body inclined less than 3°.

7) When use camera with C-mount, the camera sensor size should be less than

2/3”, weight not more than 2.5kg.

Maintenance

1) All lenses must be kept clean. Fine dust on the surface of the lens should be

blown off with hand blower or wiped off gently with a soft lens tissue;

Fingerprints or oil marked on it should be wiped off with a tissue moistened with

a small amount of xylene or a 3:7 mixture of alcohol and ether.

2) Never use the organic solution to clean the other surface (especially the plastic

surfaces). If necessary, please choose the neutral detergent.

3) Do not take the microscope apart for fearing that it is damaged.

4) After using, cover the microscope with the dust-cover provided and store it in a

dry and clean place free from moisture to prevent rust.

3. Operation

Fig.1

3.1 Use black and white work

board

(1) If the specimen is white or transparent, make the black one as

background, to enhance the contrast.

(2) Take off or change the work board, move the work board (Fig.1)

make one side down, then the other side will be up.(Fig. 1)

Adjust the degree of tightness of the focusing

arm.

Loose

Fig.2

Tension

(1) If you want to adjust tightness of the focusing arm, you can

hold one of the focusing knobs and turn another one to attain a

suitable tightness. The degree of tightness relies on the

direction to be turned. The reverse direction is tight, otherwise, is

loose.

(2)The suitable position of tightness can make the adjustment

more comfortable and prevent the focusing bracket from slipping

down by its weight during the observation. (Fig.2)

Set the specimen slide

(1) Set the specimen on the center of stage plate. If necessary,

clamp the slide with the clips.

(2)Turn on the light.

Adjust the specimen slide

(1) Turn the zoom control knob to the maximum magnification.

(2) Turn the diopter adjusting rings to the zero.

(3) Observe the specimen through the right eyepiece and make

the image clear by turning the focusing knob.

(4) Rotate the zoom control knob to the minimum magnification.

(5) Observe the specimen through the right eyepiece and make

the image clear by turning the right diopter adjusting ring.(Fig.3)

(6) Re-do the step(3)and (5) till the right adjusting ring is more precise.

(7) Do the step (4) and make the image clear which is observed

through the left eyepiece by turning the left diopter adjusting ring.

Mount and Remove the Optional Eyepiece

Micrometer

(1) Turn and remove the mounting ring from the eyepiece.(Fig.5)

(2) Clean the eyepiece micrometer and mount it to the mounting

with the inscription side downward.

(3) Gently twist the mounting ring with the eyepiece micrometer

into the eyepiece till tightening securely.

(4) To remove the eyepiece micrometer, take down the mounting

ring by twisting and take out of the micrometer, and then wrap it.

Auxiliary

objecive

Fig.8

Use Auxiliary objective

(1) Connect the Auxiliary objective to the thread at the bottom

of the microscope head.

(2) 0.5x Auxiliary objective has long working distance. When use

0.5x auxiliary objective, release the lock screw on the arm by

a 4mm Allen key, move the focus arm up and fixed in the up

screw hole.(Fig 6)

0.75x auxiliary objective no need to remove arm.

Mount PK-mount and photo set

(1) Screw the PK-mount in the head, M28 screw, tight the

mount.(Fig.7)

(2) Loosen the screw on the PK-mount , take out the mount of C

type camera .

(3) Screw the C type mount in the TV photo set.

(4) Install the TV photo set into the PK-mount and lock the screw.

Focusing the TV photo set

(1) Turn the zoom control knob to the maximum magnification,

meanwhile, observe the TV set, adjust until the image is clear.

(2) Rotate the zoom control knob to the min. magnification. If the

image is not clear enough, adjust the part until the image clear.

(3) Redo the step (1), turn the zoom control knob to the maximum

magnification to check the image is clear or not. If not clear, redo

step(1)and (2), until the image is clear in all the zoom range.

Clean the working stage

(3)Double image

Interpupillary distance is not correct

Readjust it

Dioper adjustment is not correct

Readjust it

Magnification of each eyepiece is not

the same size

Mount the same size eyepiece

(4)Image is not clear

Dirt on the surface of the objective

Clean the objective

(5)Image is not clear while the focus

changing

Diopter adjustment is not correct

Readjust the diopter

Focus is not correct

Readjust the focus

(6)The image on the monitor is not

clear when the focusing knob is

turned

The

focus

video

is not correct

Readjust the focus of video to

a correct position

There is something impede the

light

Clean the working stage

(2) bulb is burned out suddenly

The voltage is too high

Use voltage regulator

Use the wrong bulb

Replace with a correct one

(3) fuse always burned out

The voltage is too high

Use voltage regulator

(4) the bulb flickers or the

Brightness is unstable

The bulb will burn out soon

Replace with a new one

The bulb was not inserted

correctly

Insert I correctly
