Operation
Indication of remaining horizontal feed
The visible and audible remaining feed indica-
tion feature informs the user during trimming
and sectioning when a remaining feed of
approximately 1 mm is available before the front
limit is reached.
The yellow LED (
41
) in the
COARSE FEED
button
lights up from the beginning of the remaining
feed. In addition, an acoustic signal is heard for
approx. 2 seconds.
The sectioning process is interrupted and the
object head stops in the upper end position.
From this point on, a remaining feed of approx.
1 mm is available.
In the remaining feed area, no more object
feeding to the knife is possible using the coarse
feed buttons.
•
Restart motorized sectioning.
The yellow LED (
41
) in the
COARSE FEED
button lights up.
•
When the front end position is reached, the sectioning process stops
automatically.
•
Upon restart, no more feed motion takes place.
•
You can continue to work on the specimen by pressing the corre-
sponding coarse feed button in the rear end position (
HOME
) and con-
tinuing with sectioning.
To do so, you must press TRIM/SECT to switch to trimming mode,
as otherwise, you cannot use the coarse feed.
If the object head is already in the remaining feed range when the
instrument is switched on, an additional acoustic signal is heard
after the software version is displayed.
•
You can continue to work on the specimen by moving it back a short
distance using the coarse feed buttons (set trimming mode!).
•
The
STEP
function is disabled in the remaining feed range.
