USER NOTICE

1. Safety Precaution

1. Carefully open the box, avoid the accessories, like lens, dropping to ground and being

damaged.

2. Check the input voltage, be sure the input voltage which signed on the microscope is

consistent with the power supply voltage, or it will bring a serious damage to the instrument.

3. Do keep the instrument out of direct sunlight, high temperature or humidity, dusty and easy

shaking environment. Make sure the stage is smooth, horizontal and firm enough.

4. To prevent the microscope body from turning over, its pivot angle must be limited to 30°.

5. .A microscope is a precision instrument. Handle it with care and avoid subjecting it to sudden

or severe impact.

6. Make sure the instrument is earthed, to avoid lighting strike.

7. Do not disassemble any part of the microscope, especially the electrical parts on the bottom

side as this may result in electric shock.

8. Use the factory supplied power cord, please.

2. Maintenance and Storage

1. All the lenses have been well checked and adjusted. It is forbidden to disassemble them

yourself.

2. The binocular viewing head and focusing unit have a compact and precise frame; please

don’t disassemble them as possibly as you can.

3. Keep the instrument clean, wipe dust regularly, and be attention to avoid contaminating the

optical elements especially.

4. The contaminations on the prism, as fingerprint and oil, could be gently wiped with a piece

of soft cloth or tissue paper, gauze which has been immersed in pure alcohol or ether.

(Note that the alcohol and ether are highly flammable, do keep them away from the

fire or potential sources of electrical sparks, and use them in a drafty roomaspossible

as you can.)

5. Do not attempt to use organic solvents to clean the microscope components other than the

glass components. To clean them, use a lint-free, soft cloth slightly moistened with a

diluted neutral detergent.

6. If the microscope is splashed by liquid during using, cut off the power at once, and wipe up

the moisture.

BestScope International Limited

7. Do not disassemble any parts of the microscope, which will affect the function or decline

the performance of the microscope.

8. Place the instrument in a cool, dry position. When not using the microscope, keep it

covered with a dust cover.

2.2 Detailed Assembly Procedure

2.2.1 Mounting binocular viewing head (Fig.1,

Fig.2)

1. Rotate the objective①into the objective mount

thread on the lower end of the zoom body ②,as ③

in fig.2.

2. Aligning the positioning pin of the zoom body③to

the positioning groove on the binocular viewing head

④, insert the dovetail mount at the bottom of the

viewing head into the mounting port on the zoom body

③, and tighten the viewing head clamping screw⑤

with provided hexagonal driver.

Note:

Working Environment Requirement:

1．Ambient temperature: 5°Cto40°C

.(41°Fto104°F), Maximum R.H: 85%.

2．High Temperature will result in a mildewing,

dew and even ruinous instrument.

3．Avoid placing the instrument in a dusty

environment. When ending your microscope

operation, please cover it with the dust cover.

4．Lay the microscope in a plan and stable

position, please.

2.2.2 Mounting binocular head (Fig.3)

Loose the clamping bolt⑦on the pillar⑥

and insert the binocular head and zoom body

assembly ⑧into the bracket of the pillar, then

screw down the bolt⑦.

2.2.3 Mounting eyepieces (Fig.3, Fig.4,

Fig.5)

1. Remove the eyepiece dust caps⑨and gently

insert two adjustable eyepieces ⑩into the

eyepiece sleeves until they stops, as in Fig.4.

2. Using the Eye Shades

When Wearing Eyeglasses:

Use with eye shades in their normal

folded-down position. This will prevent

eyeglasses from being scratched by the eyepiece

as in Fig 5.

When Not Wearing Eyeglasses:

Extend the folded eyeshades. This makes

observation easier by preventing the inverse

incidence of light from between the eyepiece and

your eyes.

2.2.4Connecting the power cord (Fig.6)

1. Turn the main switch①on “O” (off) state

before connecting the power cord.

2. Insert the power plug②into the power jack

of the microscope; make sure the connection

is well.

3. Plug the power cord ③into the power

supply receptacle safely. Make sure the

connection is well.

2.2.5 Mounting glass stage plate (Fig.7)

If necessary, the original plastic stage

plate can be replaced by a glass one.

●Both top and bottom illuminators are LEDS.

●Permitted power supply voltage:

100V～240V.

2.2.6 Mounting aperture iris

diaphragm attachment (Fig.8, Fig.9)

○Aperture iris diaphragm attachment is

optional.

1. Use the provided hexagonal driver to loose

the clamping bolt and remove the binocular

viewing head①.

2.Mounting the aperture iris diaphragm

attachment ②to the top end of the zoom

body.

3. Mounting the binocular head into the aperture

iris diaphragm attachment and tighten the

clamping bolt③.

Adjusting aperture iris diaphragm

●The aperture iris diaphragm adjustment can increase the image contrast and focus depth.

●The size of aperture iris diaphragm can be adjusted. Switch the lever to lefttoopentheaperture

iris diaphragm; to the right, to close the aperture iris diaphragm. Check the effect during

observation.

★Do not close the aperture iris diaphragm too much, or it will decrease the resolution and lead to

lack of illumination.

★Closing the aperture iris diaphragm to the minimum state will result in faintness in field of view.

In this case, adjust the aperture iris diaphragm to the half open state.

★Closing the aperture iris diaphragm to the minimum state and increase the magnification of the

zoom body will result in lack of illumination around circumference of fieldofview.

3. Adjustment and Operation

3.1 Adjusting Binocular Viewing Head

3.1.1Adjusting interpupillary distance (Fig.10)

Different users have different interpupillary distances.

So when users change, do the interpupillary distance

adjustment.

While looking through the eyepieces, hold the left and

right of the binocular assembly①and adjust the eyepieces

by opening or closing them for binocular vision until the

left and right fields of view coincide completely.

3.1.2 Adjusting diopter ring (Fig.11, Fig.12)

1．Set the dioptor rings of both eyepieces to “0”position.

(Do this when users change, because different users

have different diopters.)

2．Place an easy-to-observe specimen on the stage plate.

3．Rotate the zoom body knob ③to the highest

magnification 5×(or 6.4×,or10×), and turn the

focusing knob④to focus the specimen.

4．Rotate the zoom body knob ③to the lowest

magnification 0.8 ×, looking only into the left

eyepiece, adjust the diopter ring on left eyepiece to

focus the specimen. Then do the same thing for the

right one.

5．Repeat item 3 and 4 until the specimen image can

always focus without any adverse effect of the

changes of magnification on the definition of the

image.

Fig.11 shows the focusing part of Stereo

Microscope BS-3060A, BS-3060B;

Fig.12 shows the focusing part of Stereo

Microscope BS-3060C.There are coarse focusing

knob ⑥and fine focusing knob ⑦in this kind of

microscope.

●The working distance of the objectives listed in

standard outfit is all 78mm for these three kinds of

stereo microscopes.

When 2×objective is chosen , it is necessary to

mount the binocular head bracket ⑤onto the lower

position. Remove the clamping bolt with provided

hexagonal driver and move the bracket down to the

lower position and set it with original bolt (Fig.11).
