5.2 Introduction to commissioning
Following commissioning, the pressure transmitter is immediately ready for use.
To obtain stable measured values, the pressure transmitter needs to be allowed to warm up for around 5 minutes after the
power supply is switched on. When it starts up, the pressure transmitter goes through an initialization routine (display at the
end: "Init done"). If the pressure transmitter does not complete the initialization routine, check the auxiliary power.
The operating data must correspond to the values specified on the nameplate. If you switch on the auxiliary power, the
pressure transmitter is in operation.
The following commissioning cases are typical examples. Configurations different from those listed here may be meaningful
depending on the system configuration.
