* If the pressure difference
between the vacuum for
degassing and the expect-
ed vacuum for distillation is
very small (distillation vac-
uum >75% of the degas-
sing vacuum), select the
function ”Auto ” (adapting
the vacuum starting from
the current pressure) in-
stead of ” Auto
➜
” (at first
searching the boiling point
automatically, and then
adapting the vacuum).
Application example
The timeline in the diagram adapts automatically to the process time.
+
Press the selection knob twice to return to the standard display.
The most recent process (except in ”VACUULAN” function) is stored in
the temporary data memory as long as the controller stays switched on.
This program can be transferred to a storage space and edited.
Once the program is finished, the clock symbol starts to flash. Confirm
the end of the program by pressing START/STOP (clock symbol will dis-
appear).
Attention: If ”Autostart” is set to ”On”, the program will start again
(time will be reset to 00:00:00) after a power failure or after switch-
ing the controller off/on. Only if the end of the program (clock symbol
flashing) has been confirmed by pressing START/STOP, the program will
not start again.
Attention: If the controller is set to ”Defaults”: ”On”, all stored pro-
grams will be deleted.
