2-4 SETTING SECTION THICKNESS

AND TRIMMING THICKNESS

The required section and trimming thicknesses are

set by means of the control knob (fig. 4.3), which is

situated on the side part of the operating panel (fig.

4.1).

To choose between section thickness and trimming

thickness, press the operating knob (fig. 4.3). A

marking (fig. 5.5) in the first line of the display

shows which cutting thickness is selected.

Switching over from trim sectioning to fine

sectioning via the operating knob (fig. 4.3) can also

serve to reduce the motorized cutting speed (see

part 2-6-3).

If the trimming thickness is chosen, the LED in

button (fig. 5.14) lights up in addition to the marking

on the display.

After turning on the instrument, section thickness

setting is automatically chosen and shown

accordingly.

When turning the operating knob, slight resistances

can be felt. The selected values are shown in the

second line on the display (fig. 5.7) of the operating

panel.

"FEED" = selected section thickness

"TRIM" = selected trimming thickness

The graduation of the section thicknesses is divided

into 5 ranges:

range graduation

up to 5µm 0,5µm

from 5µm to 20µm 1µm

from 20µm to 30µm 2µm

from 30µm to 60µm 5µm

from 60µm to 100 µm 10µm

1 2 ... 15 16 17 18 19 20 21 22 23 24 25 ... 58 59
