1. Microscope part

1. Remove the dust cover and turn on the power.

2. Put the sample on the spacer of the stage, adjust the coarse/fine adjustment knob to adjust the focus until the observed image is clear.

3. Adjust the position of the stage, find the field of view you care about, and conduct metallographic analysis.

2. In order to ensure the service life and reliability of the system, the metallographic analyzer should pay attention to the following:

1. The test room should have three anti-conditions: shockproof (away from the source), moisture-proof (use air conditioner, dryer), dust-proof (floor on the ground); power supply: 220V±10 percent , 50HZ; temperature: 0 degree —40 degree .

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

3. Do not switch the objective lens when the center of the round hole of the stage gasket is far away from the center of the objective lens, so as not to scratch the objective lens.

4. Don't adjust the brightness suddenly, and don't be too bright, which will affect the service life of the bulb and also damage the eyesight.

5. For all (function) switching, the action should be light and in place.

6. Turn off the brightness to the minimum.

7. Non-professionals should not adjust the lighting system (filament position lamp), so as not to affect the image quality.

8. Pay attention to high temperature when replacing the halogen lamp to avoid burns; be careful not to directly touch the glass body of the halogen lamp with your hands.

9. When the machine is not in use, adjust the objective lens to the lowest state through the focusing mechanism.

10. When the machine is turned off and not in use, do not cover the dust cover immediately, and cover it after it cools down. Pay attention to fire prevention.

11. Optical components that are not frequently used are placed in a drying dish.

12. Non-professionals should not try to wipe the objective lens and other optical components. The eyepiece can be wiped with a cotton swab dipped in a 1:1 ratio (absolute alcohol) mixed liquid and dried. Do not use other liquids to avoid damage to the eyepiece.

3. Computer and image analysis system
Metallographic analyzer is to adjust the observation/photograph switching knob on the metallographic microscope to the PHOT position, and the information observed in the metallographic microscope will be converted to the video interface and camera. Turn on the computer and start the image analysis software to observe Real-time images from metallographic microscopes are collected and processed after finding the field of view of interest. After the information is transmitted to the computer, the software controls whether the rating is automatic or assisted.
