11. Use of the microscope

11.1 Light intensity adjustment

Operate on the light intensity adjustment knob to turn ON / OFF
the microscope and to increase / decrease the illumination
voltage ①. (Fig. 9)

11.2 Coarse focus tension adjustment

• Adjust the tension using the provided tool.
The coarse knob tension is pre-set in the factory.
1. To modify the tension according to personal's needs, rotate
the ring ② using the provided tool (Fig. 10).
• Clockwise rotation increases the tension.
• If the tension is too loose, the stage 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.

11.3 Focus stop lever

The upper limit knob has two functions: prevent the contact
between slide and objective and acts as "focus memory".
1. After focusing the specimen, pull the lever
front of the microscope and lock it. (Fig. 11)
• In this way the focus upper limit is set.
2. Now one can lower the stage with coarse focus knob, replace
the specimen and raise again the stage up to the upper limit:
specimen will be in approximate focus and will need a fine
adjustment to get the proper focus.
• Fine focus movement is not affected by the coarse
focus lock.
• To unlock, move the lever in the opposite direction to the
one used for the locking.

11.4 Stage

with coverlside 0.17mm.
It is possible to place two slides side by side on the stage. (Fig.
