Before using BS-6004 series
Inverted metallurgical microscope is used to discern and analyze organizational structure from kinds of metal. It is
very important in the work of quality research for foundry, smelt, heat treatment and inspection for raw material
and analysis for metallurgical structure of material after processing. It is also the important tool of research work
for metal physics, which is wildly used in enterprise, university and R&D.
1. Attention:
1.1 As the microscope is precision instruments, it should be
taken carefully and avoid impact during transportation.
1.2 Do not expose the microscope in the sun directly,
either not in the high temperature, damp, dusty or
acute shake place. Make sure the worktable is
horizontal. Following environment is required: Indoor

1.3 To move the microscope, please hold groove ①
behind and tube position ② and lay it carefully. (Fig. 1)
★It will be damaged by holding the stage, focusing knobs, tube or illuminator.
1.4 The lamp will be very hot during working, please make sure there is enough space around for dissipating.
1.5 Please connect the microscope with ground to avoid lighting strike.
1.6 Please make sure the power switch is “0”(Off)(See the left Fig) and the bulb cool down before replace the
bulb or fuse.
★Bulb: 3W LED bulb (Standard)
12V/30W halogen bulb (Philips 5761) (Optional)
1.7 It adopt wildly voltage 90~240V, and do not need any transformer. Please make sure the power supply before
using.
1.8 Please use special wires supplier by our company.

2. Maintenance
2.1 Clean the lenses gently with a soft lens tissue. Carefully wipe off oil or fingerprints on the lens surfaces with
tissue moistened with 3:7 mixture of ethanol and aether or dimethylbenzene.
★Ethanol and Aether are both flammable. Please leave them away from fire or fire source, especially during
the power switch turn on and turn off.
2.2 Don’t use organic solution to clean the surfaces of the microscope, especially for plastic parts. Please use the
neutral detergent if necessary.
2.3 If the microscope damped by the liquid during working, please cut off the power immediately and make it
dry.
2.4 Do not disassemble or assemble the microscope to avoid damaging the capability.
2.5 After using, put on dust cover to protect microscope.
3. Safety sign
Sign
Signification
It shows the surface gets hot and don’t touch with bare hand.

switch at “-“position.
⑵Turn the knob ① for brightness to suitable. Clockwise
turning of the adjusting knob is to bright and counter to dark.
(Fig 11)
★It can protect the bulb if using under low power supply.
3-2 Focusing
⑴Put the specimen on metal stage and use objective 5X.
★Please make sure the specimen should be vertical with the
objective. If not, please fix the specimen by plasticine
⑵Adjust the diopter of right tube to “0” (See 3-4 Adjust
diopter). Observe through right eyepiece and turn the coarse
knob ① to find the image (Fig 12)
⑶Turn the fine knob ② to make the image clear.
3-3 Adjust tension of focus
If the tension is too tight or image is out of focus plane or the
stage slips down during focusing, please adjust the tension
knob ① of focus. (Fig. 13)
★The knob ① direction indicated is for loose and opposite

3-4 Adjust diopter
Diopter is ±5 and it is point to the line on tube. After getting
the clear image through right eyepiece, Please obverse
through left eyepiece with left eye. If the image is not clear,
please adjust the left diopter adjusting ring ①. (Fig 14)
★When both eyepieces have diopter, select one for
standard and adjust another. Please make sure the diopter of
standard one should be at “O” position before focusing.
3-5 Adjust inter-pupillary distance
When two eyes observe, please turn the two prism house with
the direction indicate to adjust the inter-pupillary till suitable.
(Fig. 15)
The mark “·” on left tube indicates the inter-pupillary.
The inter-pupillary range: 50~76mm
★Please remember your inter-pupillary for next observe.
3-6 Use filter
It can make the background of image softly and improve the
image more clearly through using filters. (Fig. 16)
Filter: Green, blue, red

3-7 Adjust field diaphragm
Field diaphragm can strength the image contrast by
preventing the diameter of bean of light into condenser and in
order to strength the image contrast. When the image is in the
edge of field, the objective can bring out the supper image.
⑴Turn the pole ② for field diaphragm adjusting to the most
left with counter clockwise to make the field smallest. (Fig 17)
⑵Through the eyepieces, here you can find the image of field
diaphragm.
⑶Adjust the both centering screws ① of field diaphragm to
make the diaphragm image to the center.
⑷Open the field diaphragm slowly, if the field inscribed with
its image, it indicates the diaphragm centered. (Fig 18)
⑸Please increase the diaphragm a little during operation to
make the field as circumcircle with its image.
3-8 Adjust aperture diaphragm
Aperture diaphragm controls the aperture of illumination.
The aperture of illumination should be suitable with
objective’s, then it can provide the best image and
increase depth of field.
The adjustment of aperture diaphragm is the same as
field diaphragm. Please use knob ①. Please adjust
aperture diaphragm to suitable through the contrast of
image. (Fig. 19)

⑴Set analyzer and polarizer as 2-2-7 and 2-2-8. (Please take
off filter slide when using polarizer slide)
⑵It can change position of polarizing light to rotate analyzer.
⑶When analyzer is at zero position, the analyzer and
polarizer are crossed.
3-10 Replace fuse
Before replace fuse, please make sure the power switch is at
“0” (Off) and cut off the power supply. Use screwdriver to take
off the fuse ①from fuse holder ② and replace a new one.
(Fig 21)
★The rating for fuse: 250V, 8A.
3-11 Mount and use TV device
