Adjust the viewing/photographing switch knob on the metallographic microscope to the phot position, convert the information observed in the metallographic microscope to the video interface and camera, turn on the computer, start the image analysis software, and view the real-time image in the metallographic microscope, Collect and dispose of after finding the field of interest. The metallographic microscope is a fine optical instrument. The operation steps and normal maintenance of the metallographic microscope system are as follows:

When the machine is not in use, do not cover the dust cover immediately, cover it after cooling down, and pay attention to fire prevention.

Infrequently used optical parts are kept in boring containers.

Adjust the position of the stage, find the field of view of interest, and perform metallographic analysis.

Adjust the viewing/photographing switch knob on the metallographic microscope to the phot position, convert the information observed in the metallographic microscope to the video interface and camera, turn on the computer, start the image analysis software, and view the real-time image on the metallographic microscope, Collect and dispose of after finding a caring field of view.

When the center of the circular hole of the stage gasket is far away from the center of the objective lens, do not switch the objective lens to avoid scratching the objective lens.

When focusing, be careful not to let the objective lens touch the sample, so as not to scratch the objective lens.

The brightness adjustment should not be too bright or too bright, which will affect the service life of the bulb and damage the eyesight.

The laboratory should have three precautionary conditions: shock-proof (away from the source of the earthquake), moisture-proof (using air conditioners and borers) and dust-proof (flooring in the air); power supply: 220v± 10%, 50hz; temperature: 0 ℃ 40 ℃.

Place the sample on the stage spacer and adjust the coarse/fine knob to stop coking until the observed image is clear.

Non-personnel should not adjust the lighting system (filament position lights) so as not to affect imaging ethics.

When the machine is turned off and not in use, the objective lens is adjusted to a low state through the focusing mechanism.

When replacing the halogen lamp, pay attention to high temperature to avoid burns; be careful not to directly touch the glass body of the halogen lamp with your hands.

Non-human laboratory wipes objectives and other optical components. You can use a absorbent cotton swab dipped in a 1:1 ratio (anhydrous alcohol: ether) mixture and wipe it dry. Do not use other liquids to avoid damage to the eyepiece.
