35 Leica VT1000 A
When the instrument is switched on for the first time, the blade is automatically moved back
in operating state "B" and stopped in state "C".
Each sectioning cycle needs only to be initiated by the operator. Once state "A" is activated,
the sectioning blade will advance at the operator-selected forward speed and amplitude
until it reaches the forward end-of-travel. The blade then switches into operating state "B"
automatically until state "C" is reached. It will then remain in state "C" until another cycle is
activated by the operator.
When in state "A", a momentary override of the preselected forward speed is available.
In this way, you can select the maximum feed rate for the movement between the rearmost
"ready" position and the specimen.
The retraction movement of the blade in operating state "B" always takes place at the maxi-
mum speed, regardless of the preset feed rate.
At any time during the sectioning cycle, operator override of the semi-automatic operation is
available. Thus during feed in operating state "A", the blade can be moved back in state "B"
and vice versa.
