Adjusting the amplitude

To obtain excellent sectioning results, the amplitude requires adjustment
according to the specimen type being sectioned.

To this end:

With a 2.5 mm Allen key loosen the clamping screw 

(1) 

and secure the

eccentric on the bottom with your finger.
Selectable amplitude positions are, from left to right:
0.2 mm; 0.4 mm; 0.6 mm; 0.8 mm; 1 mm.

Slide the amplitude clamping screw to the desired amplitude position
and retighten.

When adjusting the amplitude setting, do not remove the clamping
screw, simply loosen it.
The instrument is shipped with the amplitude set to 0.6 mm.
