3-4 SETTING SECTION THICKNESS AND
TRIMMING THICKNESS
• The required section and trimming thicknesses
are set by means of the control knob (fig. 9.1),
which is placed on the side part of the
operating panel.
• To choose between section thickness and
trimming thickness, press the control knob (fig.
9.1). The selected thickness range is then
marked with a rim when in the operating mode
NORMAL.
Note:
Whenever the instrument is turned on,
"FINE" sectioning is automatically
selected and shown accordingly (fig.
10.1).
FINE = pre-selected section thickness
TRIM = pre-selected trimming thickness
The graduation of the section thicknesses is
divided into six ranges:
Range: Graduation:
up to 2 µm 0,5 µm
from 2 µm to 10 µm 1 µm
from 10 µm to 20 µm 2 µm
from 20 µm to 30 µm 5 µm
from 30 µm to 40 µm 10 µm
from 40 µm to 100 µm 20 µm
The graduation of the trimming thicknesses is
divided into four ranges:
Range: Graduation:
up to 10 µm 5 µm
from 10 µm to 100 µm 10 µm
from 100 µm to 200 µm 20 µm
from 200 µm to 500 µm 50 µm
