AMPLITUDE rotary knob This knob controls the relative amplitude of the lateral excursion of
the sectioning blade vibratory movements.
• In the zero position (‘0‘) or during the retraction movement of the
cutting head, the blade does not vibrate.
• The maximum amplitude (2.0 mm) is reached when the rotary knob
is in the ‘10‘ position. At intermediate settings, the amplitude will
vary proportionally.
All configured values are active during the feed movement of
the cutting head only.
The amplitude can also be changed during the sectioning pro-
cess.
LIGHT switch

This simple switch switches on the fluorescent lamp and thus im-
proves the illumination of the specimen tray. Switch position:
ON --> Light is on.
OFF --> Light is off.
