Specimen Course Feed - Thermo Scientific HM340E Operation Manual

Specimen Course Feed

After changing the specimen or moving the knife or knife carrier,
it is necessary to adjust the specimen to the knife edge again.
This can easily be done by means of the specimen coarse feed
and the defined trimming values.
For fast forward and backward moves between specimen and
knife edge, the microtome has a motorized coarse feed system.
•
The specimen holder is moved to the front as long as
knob [B] for activating the coarse feed forward.
The feed speed is controlled by the turn angle. When knob [B] is
only slightly turned forwards, the speed is slow. The speed will
increase by turning knob [B] further towards the front.
•
To move the specimen holder backwards, turn the knob
[B] back- wards, i.e. in the opposite direction of the
user.
Turn angle increase will cause higher return speed.
If knob [B] is kept at a high speed for more than two seconds, the specimen will automatically move to the rear
position.
Automatic return movement can be stopped by briefly turning knob [B] in the opposite direction.
The coarse feed motor turns off after having reached the back end position.
When the specimen orientation is in the front end position, the red LED arrow (pointing downward) on the
operating panel lights up.
When the specimen orientation is in the back end position, the red LED arrow (showing upward) on the
operating panel lights up.
Press the knob [B] to release trim feed with the selected value, even if the fine mode is active.
