ATTENTIONS
1. Disassembly only by the professionals
The microscope has been adjusted before shipping, Unprofessional-person
should not disassemble and remove any other parts. Disassemble and remove
any other parts will result in equipment damage .
If you have any questions, please contact with manufacturer or local
distributor.
2. Note the input voltage if correspond
This instrument designed for wide input voltage (100V~240V,50/60HZ),
applicable to most area. But if the supply voltage exceeds this range, the
instrument will be seriously damaged.
3. Prevent burns and fire
When using power equipment, bulbs and collecting mirror and other nearby
parts of the set will rise sharply in temperature until it reaches a thermal
equilibrium state. Pay attention to anti-hot logo, they should be careful not be
burn when in use.
Alcohol, gasoline, paper and other flammable materials can’t near the
lamp in case of fire.
4. Notes on replacing the bulb
Replacement should be based on the identity of the instrument using the same
specifications of the bulb (3.4V/3W LED or G4 12V/20W halogen), otherwise
it may cause equipment damage.
The power supply must be cut off before bulb replacement, the bulb must be
cooled off completely before proceeding! Don’t left fingerprints,dust or oil on
the bulb.
5. Carry and operation
Power must be cut off before moving. Be careful not to crush your finger
when placed.
This instrument is a precision instrument, and it should be handle with care, severe
shock can cause serious damage to equipment-related parts.
The required available environment for using of the equipment:
Indoor temperature: 0 ℃ ~ 40 ℃ Maximum relative humidity: 85%
High temperature or high humidity may cause mildew, fog or dew of the
optical components, and make the instrument not work.
6. This eletrical instrument don’t cause electromagnetic interferernce for other
device.

3. Installation and use
3.1 Installation
B series microscope with whole package is convenient for installation.
Open the package carton, and insert eyepiece into the eyepiece tube of the head
(eyepiece for monocular microscope has been inserted before packing). If
objectives don’t be fixed, please take objectives out from objectives packing box,
5
and drive them into the holes of nosepiece orderly and tightly according to the
multiplying power in order.
Take out the oil bottle and dust cover, and place it properly for convenient use.
▲Please totally take out the devices in the packaging box.
▲Please don’t throw package waste away freely to protect the enviroment.
3.2 Use
3.2.1 Power Supply
Make sure the supply voltage meets the instrument’s requirement, then plug
in the socket. Rotation potentiometer with switch used by the instrument is
for protecting lamp, in case high electric current shock , prolong service time.
3.2.2 Place sample（Fig.2）
Please place specimen on the stage, and the face with cover glass should
be up, then clip it with clamp.
Clipping specimen should be careful in order to avoid spoiling glass. Place
specimen on the stage levelly.
Making the specimen into optical path by adjusting vertical moving knob
and horizontal moving knob.
3.2.3 Condenser（Fig.2）
1．Condenser up-down
Turn the condenser up-down knob to adjust the distance between condenser
front and the specimen, and change the equal illumination to obtain the best
brightness.

2. Aperture diaphragm adjustment
Rotating the handle of aperture diaphragm of condenser to adjust diaphragm
size can adjust the contrast of the specimen.
In general, aperture diaphragm can be adjusted to 70% or 80% of objective
exit pupil diameter , will get good image with best contrast.
3.2.4 Adjustment of interpupillary distance and diopter (Fig.3)
1. Adjustment of Interpupillary Distance
Please adjusting binocular tube to make left and right field coincide completely .
▲Interpupillar distance is different for everyone, so interpupillar distance
should be adjusted before using binocular microscope.
2. Adjustment of diopter
As focusing for binocular, user should observe right eyepiece with right eye, and
make the right eyepiece clear by focusing adjustment, then observe the left

eyepiece, at the same time, adjust the diopter ring of the left eyepiece
tube(diopter difference compensation)to make the image of left eyepiece clear as
same as the right eyepiece.
3.2.5 Focusing unit（Fig.4）
Usually 10X objective with large field of view and long depth of field should
be used for focusing adjustment first.
Take 10X objective into bright path, then observe the specimen with right
eyepiece by right eye and turn coarse focusing knob to find the image, then turn
slowly fine focusing knob to make the image clear.
All objectives of our microscope are precisely adjusted, and approximate
clear image should be found with the other objectives after getting the clear
image with 10X objective. If the image isn’t enough clear with the other
objectives, please turn fine focusing knob slightly to find the satisfactory image.
▲Don’t rotate the left & right coarse and fine focusing knobs in reverse
direction at the same time, if so, the focusing system will be damaged.
▲Don’t directly pull objective to turn nosepiece when user changes the different
objectives,if so, optical quality of microscope possibly be affected.The right way

is to take the tooth-like part of the nosepiece to turn it, and make the objective
into correct position and into the bright path.
3.2.6 Use of tension adjustment knob (Fig.4)
The tension adjustment ring can adjust the tension of the coarse and fine
focusing unit to prevent the stage from sliding down automatically and to
improve the comfort of operation. Rotation clockwise makes tension decrease,
and by contraries, rotation counterclockwise makes tension increase.
3.2.7 Use of oil immersion objective
The 100X objective can be used for observation even if without immersion oil.
But little non-synthetic resin immersion oil or distilled water between the
objective and specimens will fully grasp the objective function , bubbles and
impurities can’t in immersion oil which will affect image.
after adjusting with the 40X objective, adding moderate immersion oil
between the front lens of 100X objective and the cover glass of specimen can
make the image clearer. Please pay attention that air bubble and impurity can’t
be in the immersion oil, otherwise, the image would be affected.
▲After immersion oil used, the oil of specimen and the microscope surface
should be cleaned with absorbent cotton, lens paper, gauze or soft cotton cloth
with moderate mixture of pure industrial alcohol and ether (proportion 1:4)
▲Standard thickness 0.17mm cover glass should be chosen when high times
objective used, and thickness error should be within 0.01mm, otherwise, image
definition wouldbe affected.

3. 2.8 Use of powersupply
Plug the power line in base socket（Fig.5），plug the other end of power line
into power socket. Adjusting LED lamp brightness by slide the base switch.
Fig.5 Replacement of fuse
3. 2.9 Reflector （Fig.6）
Reflector is optional accessary ,only use without electricity provided.
When use 100X objective ,not recommend reflector for illumination.
Carefully remove the collector from the base and connecting the
reflector with the base.
Turning the reflector around the vertical axis so that the reflective side will
face to the light direction.At the same time around the central axis to rotate the
reflector, reflecting surface and horizontal plane is roughly 45°angle,making the
light totally shining on the specimen.Concave mirror is suitbale for large area
outdoor lighting source ,such as bright sky etc.
3. 2.10 Cautions after use
Power of microscope should be turned off after using(turning
potentiometer with click voice means be closed）, and the plug should be
