Metallographic microscope routine maintenance, maintenance and precautions
1. The test room should have three defence conditions: shockproof (away from the source of shock), moisture-proof (using air conditioning, dryer), dust-proof (the ground on the floor); power supply: 220V +-10%, 50HZ temperature: 0 degrees -40 degrees.
2. When focusing, pay attention not to make the objective lens touch the specimen, so as not to scratch the objective lens.
3. Do not switch the objective lens when the position of the centre of the gasket hole of the carrier table is far away from the centre of the objective lens to avoid scratching the objective lens.
4. Brightness adjustment should not be too big or too small, and do not over-bright, affecting the service life of the bulb, but also damaging to the eyesight.
5. All (function) switch, the action should be light, to be in place.
6. Turn off the machine to adjust the brightness to * small.
7. Non-professionals do not adjust the lighting system (filament position lamp), so as not to affect the quality of imaging.
8. Replacement of halogen lamps should pay attention to high temperatures to avoid burns; be careful not to use your hands to directly contact the glass body of the halogen lamp.
9. When the machine is switched off and not in use, the objective lens will be adjusted to the * low state through the focusing mechanism.
10. When the machine is turned off and not in use, do not immediately cover the dust cover, to be cooled down and then covered, pay attention to fire prevention.
11. Infrequently used optical parts placed in a dry dish.
12. Non-professionals should not try to wipe the objective lens and other optical components. The eyepiece can be wiped with a degreasing cotton swab dipped in 1:1 ratio (anhydrous alcohol: ether) mixed liquid after drying, do not use other liquids to avoid damage to the eyepiece.
