1. Application
This microscope is ideal for science educators, industrial enterprise, scientists and
practitioners.
2. 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.
9. Warning against electric shock.
10. Warning: before use, carefully read the manual .improper use could result in
personal injury to the user and/or damage to the equipment.
3. 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
room as possible 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.
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.

Note:
Working Environment Requirement:
1. Ambient temperature: 5℃to 40℃. (41℉
to 104℉), 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 horizontally in a
stable place please.

1. Rotate the left and right brightness adjusting
switches①clockwise until the off state before
connecting the power cord②.
2. Insert the power plug②into the power jack of
the microscope; make sure the connection is
well.
3. Plug the power cord③into the power supply
receptacle safely. Make sure the connection is
well.

3. Adjustment and Operation BS-3015
3.1 Adjusting Binocular
Viewing Head
3.1.1 Adjusting interpupillary
distance (Fig.7)
Different users have different
interpupillary distances. So when users
change, re-do the interpupillary distance
adjustment.
Looking through the eyepieces, hold the
left and right side of the binocular
assembly①and adjust the eyepieces by the
direction shown in Fig.7until the left and right
fields of view coincide completely.
3.1.2 Adjusting diopter ring (Fig.8)
1. Set the dioptor rings of both eyepieces to
“o” point. (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 knob③to get the
highest magnification, and turn the
focusing knob④to focus the specimen.
4．Rotate the zoom body knob③to get the
lowest magnification, looking only into
the left eyepiece, adjust the diopter
ring②on left eyepiece to focus the
specimen. Then do the same adjustment
for the right one.
5．Repeat steps 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.

3.2 Focus Adjustment
3.2.1 Adjusting the rotation tension of
the focusing knob (fig.9, fig.10)
1．Rotate the focusing knob①to move the
slider②to a lower position for fear that the
zoom body drops down suddenly if the
tension is decreased too much.
2．Hold the focusing knobs①with both hands,
stop the left knob and rotate the right knob
to increase or decrease the focus knob
tension.
3. Rotate both the focusing knobs in the same
direction (otherwise it will get loose) to
move the zoom body up and down to focus
on the specimen.
3.2.2 Changing the magnifications
1. The zooming knobs located at two sides of
the zooming body could change the
magnification of the specimen image.
2. Total Magnification = Magnification of
zoom body magnification of eyepiece.
Note: While using the auxiliary objective, it
should be multiplied by its magnification
in addition.
3.2.3 Illumination
1. Use LED lamps for both top and bottom
illumination.
2. Brightness adjustment (Fig.10): the right
brightness adjustment knob③is used to
adjust the bottom illumination, and the left
brightness adjustment knob④is used to
adjust the top illumination. Each knob has
its own on-off. Rotate anticlockwise to open
the power and increase the brightness,
keeping rotating clockwise would decrease
the brightness until it is power off.
