7.14
Measured value display
Introduction
You can use this function to set one of three options for the device display:
•
Display in mA
•
Display in % (of the set measuring range)
•
Display in terms of a physical unit, e.g. bar, l, m3/ h etc.
Description
If the Primary Variable is mapped to the "Pressure" device variable, you can configure the
displayed pressure unit with an add-on, GAUGE (G) or ABS (A). The add-on has no effect
on the real measured value.
To do so, select the option Gauge or Absolute under the "Pressure display type" menu
command.
There are two options for the display:
•
If the pressure unit is < 5 characters, an A or a G is added at the end, respectively.
•
If the pressure unit is ≥ 5 characters, the letters GAUGE or ABS flash alternately with the
pressure unit.

Note
The change of the display with GAUGE or ABS does not change the physical pressure
used by the transmitter, rather only the nature of the display.
