5. Operation
5.1.3 Display and control elements 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.
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 drive can be used in STEP mode, or with
continuous feed. The instrument is delivered with continuous feed (standard
configuration).
Setting the section thickness/trimming section thickness
Adjust these settings using the - keys on the control panel.
Section thickness setting range: 0.50 µm - 100 µm
Setting values: from 0.5 µm - 5.0 µm in 0.5 µm increments
from 5.0 µm - 20.0 µm in 1.0 µm increments
from 20.0 µm - 60.0 µm in 5.0 µm increments
from 60.0 µm - 100.0 µm in 10.0 µm increments
Trimming section thickness setting range: 1 - 600 µm
Setting values: from 1.0 µm - 10.0 µm in 1.0 µm increments
from 10.0 µm - 20.0 µm in 2.0 µm increments
from 20.0 µm - 50.0 µm in 5.0 µm increments
from 50.0 µm - 100.0 µm in 10.0 µm increments
from 100.0 µm - 600.0 µm in 50.0 µm increments
Selecting the sectioning and trimming mode
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 thickness
between 1.0 and 600 µm is displayed.
