9.2 Parameter assignment over device with display
Introduction
This section describes all parameters that you can reach over the device with a display.
You will find information on operating the device with display in the section Operating the device
with display (Page 76).
You can find the list of available parameters with ID and parameter name in the section List of
parameters on the display (Page 78).
9.2.1

Pressure units [01]

With the "Pressure units" [01] parameter, you select the unit of the "Pressure" (P1) measured
value that is displayed in the measurement view.
You can find a description of the pressure units that you can set in the section Display of the
pressure units (Page 107).
With the "Pressure reference" parameter [33], you adapt the display of the pressure units to
your application, if necessary (absolute pressure or gauge pressure).
Both parameters are available using a local operation or over the remote operation.
