Metallographic microscope is the traditional optical microscope and computer (digital camera) through photoelectric conversion organic combination, not only can be observed on the eyepiece, but also can be on the computer (digital camera) display screen to observe real-time dynamic images, and the computer metallographic microscope and the required pictures for editing, saving and printing.
Common faults and solutions of metallographic microscope:
1. The light bulb of the metallographic microscope is bright but the light in the field of view is very dark. Possible causes and solutions:
1> The field of view stop is not wide enough, it is enough to open the field of view stop;
2> Set the dimmer hand wheel too low, adjust it to the appropriate position;
3> If you use the deflector and deflector insert board, pull out the insert board.
2, the edge of the field of view of the metallographic microscope is dark or uneven. Possible causes and solutions:
1> The converter is not in the positioning position, turn the converter to the positioning position;
2> If there is something dirty on the eyepiece or objective, clean the eyepiece or objective;
3> Insert the insert plate or remove the light path if the insert plate of the filter, polarizing mirror and polarizing mirror is not in the correct position.
3, metallographic microscope bulb is not bright. Possible causes and solutions:
1> No power supply, connect the power supply;
2> Bulb wire plug-in connection is poor, correctly connected;
3> Bulb installation is not correct, correct installation;
4> The bulb is burned out, replace the bulb.
4, metallographic microscope rough hand wheel is very tight. The reason is that the elastic adjustment ring lock is too tight, relax properly.
5. The stage descends by itself and cannot stop on the focal plane during observation. The reason is that the tightness adjustment is too loose, properly lock.
6, metallographic microscope in the use of the site does not pay attention to dust, moisture, resulting in the eyepiece or objective lens is very dirty to see, this time must not wipe yourself, it is easy to wipe more dirty, it is likely to no longer clean out, so we need to find professionals to deal with.
