General functions
3.2.1
Manual distillation
The set point of system pressure is input. When the distillation
starts, the system pressure is reduced to the input value and
kept constant. An input value stays in the memory even when
the apparatus is turned off. Distillation must be stopped
manually.
3.2.2
Distillation with timer function
The set point of system pressure and distillation duration are
input. When the distillation starts, the system pressure is
reduced to the input value and kept constant during the
selected period. At the end of the input distillation period, the
distillation is stopped. If configured accordingly, rotation of the
evaporating flask is stopped and the flask is lifted from the
bath (see 5.6 Configuration).
3.2.3
Working memory
The last module used and associated values remain in the
working memory after the apparatus is turned off and are
automatically recalled when the apparatus is turned on again.
