3-7-1 COARSE FEED AND SPEED FOR
COARSE 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 the fast forward and backward travel between
specimen and knife edge, the microtome has a
motorized coarse feed system.
•
The specimen holder is moved to the front as
long as the knob (fig. 26.2) for activating the
coarse feed forwards, i.e. in the direction of
the user, is turned.
•
The feed speed is controlled via the turn
angle. When the knob is only slightly turned
forwards, the speed is slow. Turn the knob
further towards the front, the speed will be
higher.
•
To move the specimen holder backwards, turn
the knob (Bild 26.2) backwards, i.e. in the
opposite direction of the user.
•
Turn angle increase will effect higher return
speed.
•
In case the knob is kept for more than two
seconds at a high speed, the specimen
movement automatically moves in its rear end
position. The knob can then be released.
•
The automatic return travel can be stopped by
turning the knob briefly in opposite direction.
•
The coarse feed motor turns off after having
reached the rear end position.
•
When the front end position of the specimen
movement is reached, the red LED arrow on
the operating panel (fig. 27.2) lights up.
•
When the rear end position of the specimen
movement is reached, the red LED arrow on
the operating panel (fig. 27.1) lights up.
•
Press the knob (fig. 26.2) to release trim feed
with the selected value, even if the fine mode
is active.
