Caution!

Specimen retraction
To prevent damage to the blade and specimen, the specimen is moved
away from the blade during the return motion to the upper home position.
In motorized sectioning mode, the retraction depends on the setting of the
sectioning speed.
In manual mode, the retraction value can be selected in 5 μm increments
between 5 and 100 μm. Specimen retraction is set to 10 μm at the factory.
The specimen retraction can also be deactivated for the manual and
motorized operation if required.
The selected setting is maintained when the instrument is turned off.

sum of the section thicknesses in μm for all sec-
tions completed since the instrument was
switched on.
(Section thickness sum)
When the
ΣΣΣΣΣ
