The ‘RETURN’ key may now be used
to retract the head to the position you
had selected as the start position
above. Before the head retracts the
bath will be lowered so that the blade
does not drag across the surface of
the specimen. After the head has been
retracted the bath will be raised to its
previous position and then raised once
more by the thickness of the section in
readiness for another cut.
When the cutting head has been retracted to the start position, the section thickness
will be highlighted on the display. If required, the section thickness may be changed
by pressing the height button and making any adjustment required via the rotary
control knob. Note that this will change the section thickness for this slice only. If you
want to change the repeat thickness this should be done by changing the general
operating parameters – see the section above ‘Changing the operating parameters’.
The cut may now be repeated as often as you wish (7000smz only). If you want to
make repeated cuts using the same parameters the automatic repeat can be used –
see the next section ‘Automatic Operation’.
