9. Use of the microscope

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.5)
2. Coarse focus tension adjustment
► Adjust the tension using the provided
tool.
The coarse knob tension is pre-setted in the
factory.
To modify the tension according to personal's
needs, rotate the ring ② using the provided
tool (Fig. 6).
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.
3. Coarse upper limit knob (Fig. 7)
The upper limit knob has two functions: prevent
the contact between slide and objective and
acts as "focus memory".
After focussing the specimen, rotate the knob
③ and lock it. In this way the focus upper
limit is set. 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 knob in the
opposite direction to the one used for
the lock.
4. Stage (Fig. 8)

thickness 1,2 mm with coverlside 0,17mm.
It is possible to place two slides side by side
on the stage.
• Open the spring arm of the slide
holder ④ and place frontally the
slides on the stage.
• Gently release the spring arm of the
slide holder.
► A sudden release of the the spring
arm could cause the falling of the
slide.
