10. Use of the microscope
10.1 Microscope switch on
Put the main switch ① to "I" (ON) to turn on the microscope. (Fig.
17)
10.2 Light intensity adjustment
Rotate the light intensity adjustment knob ② to increase /
decrease the illumination voltage. (Fig. 18)
10.3 Coarse focus tension adjustment
The coarse knob tension is pre-set in the factory.
1. To modify the tension according to personal's needs, rotate
the ring ③. (Fig. 19)
• Clockwise rotation increases the tension.
• If the tension is too loose, the nosepiece could go lower by
itself or the focus easily lost after fine adjustment. In this
case, rotate the knob in order to increase the tension.
10.4 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 ② to
compensate. (Fig. 20)
• The adjustment range is ±5 diopter. The number shown
on the diopter ring should correspond to the operator's
diopter correction.
