Entering value in Function operating mode
The desired pressure curve is entered via data points that connect
the vacuum pump system to pressure ramps.
Fig. 15: Menu for Function operating mode
Entering data points (up to 12):
1.
Time interval since the last data point: ∆ t
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.
