The lamp bulb spoilschange a new bulb 
The brightness adjustment knob is set too darkAdjust the knob in a proper position 
No use the appointed lamp bulbuse the specified halogen Lamp 6V20W 
2, The edge of the field of view has shadow or the brightness is asymmetryThe nosepiece is not in the located positionAdjust it into the located position 
The surface of the lamp become blackChange a new lamp bulb 
The filament shadow not clean upMove in Condenser adjust knob front and back to change the focus position to clean up the filament shadow. 
The surface of the lens is moldy or has contaminantClean the lens 
3, Find dust and stain in the field of viewThere are stains on the specimenChange the specimen 
There are stains on the eyepieceClean the eyepiece 
4, The image is defocus, low-resolutionThe objective damageMend and correct the objective (send to factory for overhauling) 
The lens of the objective and eyepiece is moldy or have contaminantDo cleaning

Fine focus system is brokenExamine and repair the fine focus system(send to factory for overhauling) 
The objective is not in the center of the light pathTurn the nosepiece to the located position 
5, The image focus surface incline(one side is clear and the other side is faint)The illumination light incline seriousAdjust the filament position ,let the light distributing of the field of view become symmetrical and bright 
The specimen don't correctly placePut the specimen on the right position 
The nosepiece is not in the located positionTurn the nosepiece in the required position 
1,  The eyes are uncomfortable, the left and right fields of view is not coincided .
The interpupillar distance is not correctAdjust the interpupillar distance correctly 
The diopter is not rightAdjust the diopter according your sight 
Can't adapt to binocular observation When look into the objective, do not stare at the specimen but at the whole field of view, or move the eyes away to see other things, then back into the objective 

Product Applications: 

It can be compared with eyepiece gauge measurement. 
Measurements thread pitch diameter, tooth angle, foot-shaped and other parts of the cutting tool or contour measuring microscopic zoom. 
Inspection of the work piece surface condition. Measuring angle Measuring Length. It also can be used as microscopic observation. 
Relative measurement method for detecting surface roughness of workpiece and other non-contact measurement for the purpose of a variety of sophisticated processing industry. It is one of the measuring room, laboratory and workshop indispensable measuring and testing equipment.
