User Notice BS-6023
1. Safety Symbols
symbol
explanation
Indicates that the surface becomes hot, and should not be touched with
bare hands.
Before use, carefully read the user manual .Improper use could result in
personal injury to the user and/or damage to the equipment.
Indicates that the main switch is ON.
Indicates that the main switch is OFF.
2. Safety Precautions
1. Be careful when opening box to keep objectives from dropping and damage, avoid objectives from sweat
and fingerprints.
2. Do keep the metallographic device out of direct sunlight, high temperature or humidity, dusty and easy
shaking environment. Make sure the stage is smooth, horizontal and firm enough.
3. When moving the instrument, grip two sides of the bottom of the microscope with your two hands.
★DO NOT hold the coarse-fine movement hand wheel or the lamp house or the microscope may be
damaged.
4. Please ensure enough cooling room for power box and keep away from power wires.
5. When running, the lamp house and nearby parts will be very hot. Please ensure 10cm cooling room for
them.
6. Make sure the instrument is earthed, to avoid lighting strike
7. For safety, be sure the main switch is in “O”(off) state and cut off the power supply before replacing
the bulb or the fuse. If you replace the bulb during use or right after use, allow the lamp bulb and the
lamp house to cool completely before touching.
8. Use the dedicate power wires。
9. When camera or TV lens is needed, make sure the adding weight is less than 2.8kg.

3. Maintenance and Care
1. All the lenses have been adjusted properly; do not dismount them by yourself please.
2. The nosepiece and coarse and fine focusing parts are so delicate that it is forbidden to disassemble them
carelessly by yourself.
3. Keep the instrument clean ,and do not pollute the optical element when wiping away the dust on the
instrument.
4. The contaminations on the prism, like fingerprints and oil smudges, 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. When using, if the microscope is splashed by liquid, cut off the power at once, and wipe away the splash.
7. Do not disassemble any parts of the microscope, as this will affect the function or reduce the performance of
the microscope.
8. Place the instrument in a cool, dry position. After using the microscope, remember to cover it

of the power box, plug
one head of power line to socket
○
2
and the
other head to the power supply. Toggle the
converter switch

.
The coarse focus hand wheel is in a loose state
when delivered, a heavy force is needed to rotate
the hand wheel.
3-4 Adjustment of pupil distance (pic.5)
The range of pupil distance is 47mm～78mm. when
observing with both eyes, hold and rotate the
prism table to adjust the pupil distance until the
left and right field of view coincided.
3-5 Visibility adjustment (pic.6)
1. Observing with right eye, rotate the focus hand
wheel until the sample is imaged clearly within
the eyepiece.
2. Use left eye to observe, adjust the visibility ring
○

3-6 3-gear light path switch (pic.7)
1. When not using cameras, totally push in the
light path switch rod and observing by eyepiece.
Use the 10× objective to focus, first descend the
focusing component and find the image in the
10× eyepiece, then turn the fine focusing hand
wheel until getting clear image. Convert the
objective will not touch and damage the sample
because of the parfocal.
2. When using cameras, totally push in the light
path switch rod and pull it out after getting a
clear image. Observing through videos.
