Use of the microscope in brightfield

Turning on the microscope

Move the main switch ①, placed on the left side of the micro-
scope, in the "I" (ON) position. (Fig. 10)

Adjusting the light intensity

Turn the brightness adjustment knob ②, placed on the right
side of the microscope, to increase and decrease the bright-
ness. (Fig. 11)

Adjusting the coarse focus tension

The coarse focusing knob ④ is pre adjusted to a tight tension
upon leaving the factory.
If the nosepiece drops down by itself, or the specimen de-
focuses while adjusting the fine focus knob ⑤, the coarse
focus knob is too loose.
Turning the tension adjustment collar ④ in clockwise direc-
tion tightens the coarse focus tension ③.
Rotate in the opposite direction to decrease the tension.
(Fig. 12)

Diopter adjustment

1.
Look into the right eyepiece with your right eye only, and
focus on the specimen.
2. Look into the left eyepiece with your left eye only. If the
image is not sharp, use the diopter adjustment ring ⑥ to
compensate. (Fig. 13)
The adjustment range is ±5 diopter. The number indicat-
ed on the adjustment ring graduation should correspond
to the operator's diopter correction.
