Endress+Hauser Cerabar S Series - Calibration Via a Configuration Tool

Bias pressure
If the display (when present) does not display zero after calibration when the process
pressure p
e
= 0, then it can be corrected to zero by registering the bias pressure.
# Key Entry
1 Correct display:
Press +Z and +S twice
simultaneously: An acting bias
pressure is registered
2 Display bias pressure:
Press +Z and +S once
simultaneously: An entered bias
pressure is briefly displayed
3 Delete bias pressure:
Press -Z and -S twice simultaneously:
An entered bias pressure is deleted
5.2 Calibration via a configuration tool
The calibration is made via a configuration tool (remote operation).
