Daily maintenance of metallographic microscope Metallographic microscope is a precision optical instrument. The operation steps, daily maintenance and precautions of metallographic microscope system are as follows: I. Microscope part 1. Remove the dust cover and turn on the power supply. 2. Place the sample on the stage gasket and adjust the coarse/fine adjustment knob to focus until the observed image is clear. 3. Adjust the position of the stage, find the field of view of interest, and carry out metallographic analysis. Second, the computer and image analysis system Adjust the observation/PHOTography switch knob on the metallographic microscope to phot position, and the information observed in the metallographic microscope will be transferred to the video interface and camera. Turn on the computer and start the image analysis software, so that the real-time image from the metallographic microscope can be observed, and the field of view of interest can be found and collected and processed. Three, daily maintenance, maintenance and matters needing attention 1. The laboratory shall meet the conditions of three defenses: shockproof (away from the earthquake source), moisture-proof (using air conditioner and dryer) and dust-proof (paving the floor on the ground); Power supply: 220 V 10%, 50Hz;; Temperature: 0℃-40℃. 2. Be careful not to make the objective lens touch the sample when focusing, 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 to avoid scratching the objective lens. 4. Brightness adjustment should not be too big or too bright, which will affect the service life of the bulb and impair eyesight. 5, all (function) switch, action should be light, to reach the designated position. 6. Turn the brightness to the minimum when shutting down. 7. Non-professionals should not adjust the lighting system (filament position lamp) to avoid affecting the imaging quality. 8. Pay attention to high temperature when replacing halogen lamps to avoid burns; Be careful not to touch the glass body of halogen lamp directly by hand. 9. When shut down and not in use, adjust the objective lens to the lowest state through the focusing mechanism. 10, shut down when not in use, don't immediately cover the dust cover, cover again after cooling, pay attention to fire prevention. 11. Optical components that are not used frequently 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 dipped in a 1:1 ratio (absolute alcohol: ether) mixed liquid with a cotton swab, and then wiped. Do not use other liquids to avoid damaging the eyepiece.
