5.4.3 Area 2.1 - Modes of operation
5 RUN MODE (button)
Press RUN MODE to select one of the operation modes below.
6 MAN (LED)
Emits light, when manual mode of operation MAN has been selected.
In MAN mode, area 5 is activated:
- Knife (or miller) and sledge can be moved manually (e.g. for bring-
ing the knife closer to the specimen).
- Sectioning / milling stroke limit (‘window’) can be defined.
- Section / milling thickness, retraction (area 2.2), sectioning / milling
speed as well as sledge return speed (area 2.4) can be selected.
7 AUTO (LED)
Emits light, when automatic mode of operation AUTO has been selected.
- Sectioning / milling mode (area 2.3) can be selected.
- Parameter selection in areas 2.2 and 2.4 as in MAN.
- Pressing RUN/STOP + RUN/ENABLE (or lightly pressing the foot
switch) in AUTO mode starts sectioning / milling (push to start /
push to stop).
8 PROG (LED)
Emits light, when program mode of operation PROG has been selected.
-
Parameter selection in areas 2.2 and 2.4 as in AUTO and MAN.
Additional features of PROG mode:
Preselection of a specific number ‘n’ of sections / milling strokes to be
done (LED (12) in area 2.2).
- Sectioning / milling in PROG mode (press RUN/STOP + RUN/EN-
ABLE or activate foot switch):
the preselected number of sections / milling strokes is carried out as
per the parameters defined (number of sections, section thickness
etc.); then the sledge stops in the defined stop position (area 2.5) and
an acoustic signal indicates the end of the sectioning program.
Parameters selected always remain stored until new parameters
are entered (also when the instrument mains switch (0/I) is
switched off).
