The graduation of the trimming thicknesses is divided into four ranges:
Range
up to 30 µm
from 30 µm to 100 µm
from 100 µm to 200 µm
from 200 µm to 500 µm
Trimming and First Cuts
After the specimen and the knife/blade are adjusted, further gradual feeding for trimming can be carried out
using the function "trimming mode". For different sectioning series, deeper layers of the specimen can be
reached with the function "trimming".
•
Press the knob [A] for the section thickness setting to select TRIM.
When the instrument is operating in the NORMAL display mode, the TRIM value is shown with an outline.
In this mode, turn the knob [A] to alter the value.
During each hand wheel rotation, the specimen holder is moved for- wards by the pre-selected trimming value in
the upper reversal point.
•
Press the coarse feed knob [B] for further TRIM feed.
Whenever this knob [B] is pressed, the specimen holder is moved for- ward by the amount of the pre-selected
trimming value using knob [A].
