Calling Up The Pressure Ramp; Softkey Graph; Softkey "Start All" And "Stop All - Heidolph Hei-VAP Precision Manuel D'utilisation

6.12.3

Calling up the pressure ramp

Pressure ramps can be called up via the Favorites menu.
The programmed pressure ramps can be edited when the process is de-activated by
changing the respective parameters (see chapter6.12.1).

6.13 Softkey Graph

The pressure curve is displayed in the graphic view of the actual value display. The time
is illustrated in [min] on the x axis and the associated pressure in [mbar] on the y axis.
Switching over between "graph" and "values" is not possible when
the vacuum control unit is switched off.
Only the section for which pressure values are available is shown on the pressure axis.
The displayed time range on the x axis is set in the setup. If the set time range is ex-
ceeded, the time window will be continuously shifted.

6.14 Softkey "Start all" and "Stop all"

A distillation can be started and stopped automatically by using softkey "Start all" (1)
and „Stop all" (1).
The unit is operational.
The immersion depth of the evaporator flask is set (see chapter 4.5.7).
The desired settings are completed.
Caution - Glass breakage! The immersion depth of the evaporator
flasks must be set correctly to prevent lowering of flask into bot-
tom of heat bath on motor lift models.
"Start all"
The lift moves down (only for the motor lift unit), rotation, vacuum control and timing are
started.
All parameters of the distillation can be changed during the
course of the "start all" function.
"Stop all"
The lift moves upward (only for the motor lift unit), rotation, vacuum control and timing
are stopped.
