Troubleshooting

Trouble	Causation	Remedy
Switch on but bulb dark.	Plug is unreliable	Plug in again
	Bulb is broken	Change bulb
	Fuse is broken	Change fuse
Bulb is flickering or brightness is unsteady.	Bulb is unstable	Insert it again
	Bulb is broken	Replacing bulb
Brightness of view field isn't enough or uneven.	Bulb specification doesn't meet the requirement.	Replacing bulb
	Brightness is too low.	Rotating potentiometer to adjust.
	Objective isn't in correct position.	Make the objective in correct position.
	The size of iris aperture is too small.	Adjust the size of iris aperture.
	Lens (objective, eyepiece,condenser, light collector) has dust.	Clean it
	Position of condenser is too low.	Higher condenser
Image isn't clear (contrast or definition isn't enough)	Cover glass of specimen doesn't meet the requirement.	Use required thickness cover glass. (0.17mm)
	Cover glass of specimen isn't in up direction.	Place specimen correctly.
	Surface of objective lens is dirty (especially it is easy for the front lens of 40X objective to dip in immersion oil).	Clean it
	Immersion oil isn't used for 100X objective (oil).	Use immersion oil
	Immersion oil doesn't meet the requirement.	Use immersion oil supplied by producer.
	There is bubble in immersion oil.	Clear the bubble way
	Size of iris aperture isn't proper.	Adjust the size of iris aperture.
	Position of condenser is too low.	Readjust the position of condenser.
One side of image is dark or image is moving as focusing.	Objective isn't in correct position.	Make the objective in correct position.
	Specimen isn't placed correctly.	Place specimen levelly on stage and clip it with clamp.
Objective touches specimen as changing low times objective to high times objective.	Cover glass of specimen isn't in up direction.	Place specimen correctly.
	Cover glass doesn't meet the requirement.	Use required thickness cover glass. (0.17mm)
Image observed by two eyes aren't in superposition entirely.	Interpupilary distance isn't adjusted correctly .	Adjust interpupilary distance according to two eyes.
It is easy for eyes to be tired during observing.	Diopter isn't adjusted correctly.	Readjust diopter
