2. Setpoint pressure: p (mbar) / p (bar) / p (hPa) / p (Torr)
3. Additional options ("+" column) to influence the course of the
function:
CV1: Open coolant valve (accessory):
CV0: Close coolant valve (accessory):
S: Jump – the system evacuates/ventilates to the required
pressure as quickly as possible.
A: Automatic – Automatic detection of the boiling pressure
If the set limit pressure is reached without a vapor pressure,
the program goes to the next function step.
A+: Automatic Plus – Automatic detection of the vapor
pressure with subsequent pressure reduction.
Line selection (see Fig. 13):
To change the line:
Turn the rotary/push knob.
To select a line for editing:
Press the rotary/push knob.
To edit a selected line:
To change columns:
(e.g. from ∆ t to p (mbar):
Press the rotary/push knob.
To change an entry:
Turn the rotary/push knob.
After the last column (+), the display automatically returns to
line selection and jumps to the next line.
If you are in input mode and have not entered any data within 3
seconds, the display automatically returns to line selection.
The function values of the data point table are stored in the
internal memory of the vacuum pump system when the
process starts, and are available again when there is a restart.
Changes to the function values (sampling point table) are
carried over directly from the PC software, which may be used
simultaneously.
Repeating/deleting sampling points:
The following symbols may be set in the column for the time
intervals under the value 00:00:00:
= Repetition. The desired number of repetitions can now
be specified in the field for the setpoint pressure.
…
= Deletion of the data point.
In both cases, all subsequent sampling points are automatically
deleted.
