Press the
‘SLICE ON/OFF’ key to
commence the cut. The
‘SLICE
ON/OFF
’ key will now change to a red
illumination. Use the rotary knob to
control the advance speed as the
blade moves through the tissue.
(Note that, if desired, the advance
speed can be reduced past zero and
the cutting head moved in reverse).
When the cut has been completed
press the
‘SLICE ON/OFF’ key to halt
the process.
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 After the head has been
retracted the bath will be raised to its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When the cutting head has been retracted to the start position, the section thickness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. Set a movement amount using the rotary knob. Press
the
‘RETURN’ key to raise the table by this amount. Press the ‘SLICE’ key to lower
the table by this amount. Press the
‘HEIGHT’ key once more to exit. 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. If you want to make repeated
cuts using the same parameters the automatic repeat can be used
– see the next
section
‘Automatic Operation’.
