Troubleshooting

Some problems will happen in the using of the microscope, you could solve them according the following list. If you cannot solve the problem after checking the entire list, please contact us for assistance.

	PROBLEM	REASON FOR PROBLEM	SOLUTION
* Optical Part *
1．	Illumination is opening, but the field of view is dark.	The poor contact exists in the lamp house and the illumination system.	Ensure the contact pin and the lamp holder pin work well.
		The lamp bulb spoils.	change a new bulb.
		The brightness adjustment knob is set too dark	Adjust the knob in a proper position
		No use the appointed lamp bulb	use the specified halogen Lamp 6V30W
2．	The edge of the field of view has shadow or the brightness is asymmetry	The nosepiece is not in the located position	Adjust it into the located position
		The surface of the lamp become black	Change a new lamp bulb
		The surface of the lens is moldy or has contaminant	Clean the lens
3．	Find dust and stain in the field of view	There are stains on the specimen	Change the specimen
3．	Find dust and stain in the field of view	There are stains on the eyepiece	Clean the eyepiece
4.	The image is defocus\low-resolution	The objective damage	Mend and correct the objective (send to factory for overhauling)
		The lens of the objective and eyepiece is moldy or have contaminant	Do cleaning
		The opening of Aperture diaphragm and field diaphragm is not proper, and too much astigmatism.	Change the opening of the aperture diaphragm and field diaphragm
		Fine focus system is broken	Examine and repair the fine focus system (send to factory for overhauling)
		The objective is not in the center of the light path	Turn 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 serious	Adjust the filament position ,let the light distributing of the field of view become symmetrical and bright
		The specimen don’t correctly place	Put the specimen on the right position
		The nosepiece is not in the located position	Turn the nosepiece in the required position
6．	The eyes are uncomfortable, the left and right fields of view is not coincided	The interpupillar distance is not correct	Adjust the interpupillar distance correctly
		The diopter is not right	Adjust 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
