Mangofei Optical Metallurgical Microscope Operating Procedures
Microscope part
1,Remove the dust cover and switch on the power supply.
2,Place the specimen on the carrier stage spacer, adjust the coarse/fine adjustment knob for focusing until the observed image is clear.
3,Adjust the position of the carrier stage to find the field of view to be observed for metallographic analysis.
Computer and image analysis system
The observation/photographic switching knob on the metallurgical microscope to PHOT position, the information observed in the metallurgical microscope will be converted to the video interface and the camera, open the computer, start the image analysis software, you can observe the real-time images from the metallurgical microscope, to find the observation of the field of view will be captured and processed.
Routine maintenance, maintenance and precautions
In order to ensure the service life and reliability of the system, pay attention to the following matters:
1. The test room should have three-proof conditions: shock-proof (away from the source of shock), moisture-proof (using air conditioning, dryer), dust-proof (floor on the ground); power supply: 220V ± 10%, 50HZ; temperature: 0 ° C -40 ° C.
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) switching, 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 directly touch the glass body of the halogen lamp with your hands.
9. When the machine is switched off and not in use, adjust the objective lens 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 cover, 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 a mixture of 3:7 ratio liquid after drying, do not use other liquids to avoid damage to the eyepiece.
