General information about
the cutting window
Not possible. The horizontal cutting path can be
reduced to the specimen size. The
two cutting window edges can be
adjusted and changed indepen-
dently. Holding the key down for
a longer duration (audible warn-
ing signal) sets the beginning or
end (depending on the key) of the
cutting window to the maximum
value. Smallest possible section-
ing window: 0.5 mm. If a window
smaller than 0.5 mm is set or the
user reverses the beginning and
end, the last entered value is ac-
cepted and the previous value is set
to the maximum value. The cutting
window is not saved when the in-
strument is switched off; however,
it is retained when you switch from
automatic mode (AUTO) to semiau-
tomatic mode (MAN).
Not possible. Advance the blade toward the
specimen using the "Blade for-
ward" key. Press the "1st cutting
window edge" key until the LED in
the key lights up.
Not possible. Advance the blade to the end of the
specimen using the "Blade forward"
key and press "2nd cutting window
edge" until the LED in the key lights up.
Activated cutting window edges can be deactivated
by pressing the corresponding key for approx. three
seconds.
