The value has been stored when the LED in the
sectioning window key lights up briefly.
If the LED flashes, the value has not yet been
stored, because the user has tried to set a win-
dow margin outside the possible window range
(the area in which the sectioning window can
be set is slightly smaller than the total section
stroke).
• In that case, repeat the step in question.
The sectioning window cannot be de-
leted. If need be, it can be set to maxi-
mum size (i.e. almost the entire sec-
tioning stroke will be carried out at
one and the same speed).
Every time after the instrument is dis-
connected from mains, the sectioning
window is set to maximum size upon
switching back on. This also applies
when the instrument is switched on for
the first time.
5.4.2 Setting the sectioning window
The term ‘Sectioning window’ stands for a dif-
ferent (slower) speed setting in that part of the
sectioning stroke where the specimen is actu-
ally cut, while the remaining sectioning stroke
(above and below the specimen) as well as the
retraction (return) stroke are carried out at a
higher speed level (time-saving feature).
If a sectioning window is set, speed inside the
window is as set on the control panel. Outside
the sectioning window the specimen head trav-
els at a proportionately higher speed.
Always set the sectioning window
while in the sectioning stroke (speci-
men moves downward). Setting the
window in retraction stroke (specimen
travels upward) is not possible.
• Position lower edge of specimen approx.
3 mm above the knife edge (rotate hand-
wheel clockwise).
Press sectioning window key.
• Position upper edge of specimen just below
the knife edge (continue to rotate the hand-
wheel clockwise).
Press sectioning window key once
more.
