Current value of estimated pump pressure
A rough indication of the local pressure can be estimated from the measurement of the ion current.
The pressure indication is shown on the right side, in the second line of the display and can be
expressed in Torr, Pa or mbar. The pressure units can be alternatively selected by pushing the
pushbutton
Torr / Pa / mb

5.2. Multifunctional
keys
On the front panel there are three multifunctional keys (model 3B0506).
Labels on the left of each key indicate their function during normal operation of the power supply.
Labels on top and below each key indicate their function in the setting mode.
Pressing the keys for shorter or longer period of time corresponds to different functions of the key
in various menus. This helps avoiding errors due to accidental pressures.
