To switch between sectioning mode and trimming mode, press the TRIM
SECT button. Whenever the button is pressed, the display toggles
between SECT and TRIM.
In the SECT display, the sectioning thickness in the range from 0.50 to
100.0 μm is shown, and in the TRIM display, the trimming section thick-
ness between 1.0 and 600 μm is displayed.
Adjust these settings using the
Section thickness setting range: 0.50 - 100 μm
Setting values: from

from 20.0 - 60.0 μm
from 60.0 -100.0 μm
Trimming section thickness setting range: 1 - 600 μm
Setting values: from
from 10.0 - 20.0 μm
from 20.0 - 50.0 μm
from 50.0 - 100.0 μm
from 100.0 - 600.0 μm
The electric coarse feed at two speeds is used for a rapid movement of the
specimen towards and away from the knife.
With the double-arrow buttons, the coarse feed operates at 900 μm/s; with the
single-arrow buttons, it runs at 300 μm/s. In sectioning mode, the coarse feed
can be operated in two different ways: defined step-by-step specimen feed
(STEP function) or continuous movement of the specimen. The instrument is
delivered with the STEP function deactivated (standard configuration).
Three-digit display
This display is located both on the instrument
and on the control panel.
If the SECT LED is lit up, the display shows the
section thickness setting in μm.
If the TRIM LED is lit up, the display shows the
trimming section thickness setting in μm.
