Before using A13.0905
Invert 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 temperature: 5℃～
40℃, Max relative humidity:80%.
1.3 To move the microscope, please hold
groove ①behind 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
12V/30W halogen bulb (Philips 5761)
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 anther or dimethylbenzene.
★Ethanol and Anther 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.
Read the introduction before using. Unsuitable operation would lead person hurt
or instrument faulty.

3. Operation A13.0905
3-1 Illumination
⑴After connect the microscope with power
supply, set main switch at “-“position.
⑵Turn the knob ①for 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 plasticene
⑵Adjust the diopter of right tube to “0”
(See 3-4 Adjust diopter). Observe through
right eyepiece and turn the coarse knob ①to
find the image (Fig 12)
⑶Turn the fine knob ②to 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 ①of
focus. (Fig. 13)
★The knob ①direction indicated is for

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 eyepiece 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 ②for 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 ①of
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 excircle
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)

3-9 Use simple polarizing kit
Simple polarizing kits includes polarizer and
analyzer. (Fig. 20)
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 ②and replace a new
one. (Fig 21)
★The rating for fuse: 250V, 8A.
3-11 Mount and use TV device
⑴Loose the lock-screw ①on tri-tube and
take off the tri-cap ②. (Fig 22)
⑵Take off the caps of TV adapter ③and
settle on tri-tube and lock by screw ①.
⑶Loose the lock-screw ④on TV adapter and
take off C-mount ⑤. Then set the C-mount to
CCD or Vidicon and connect to TV adapter
again, lock on.
⑷Adjust the image clear through binocular
then obverse through CCD. If it is not clear,
you can adjust the adjusting ring ⑥till clear
