Description
1 Select the "Pressure" measuring mode via the
"Measuring Mode" parameter.
Menu path: Setup → Measuring mode

WARNING
Changing the measuring mode affects the
span (URV)
This situation can result in product overflow.
‣
If the measuring mode is changed, the
setting for the span (URV) must be
checked in the "Setup" operating menu and
readjusted if necessary.

2 Select a pressure unit via the "Press. eng. unit"
parameter, here "mbar" for example.
Menu path: Setup → Press. eng. unit
3 Select the "Set LRV" parameter.
Menu path: Setup → Extended setup → Current
output → Set LRV
Enter the value for the "Set LRV" parameter
(here 0 mbar) and confirm. This pressure value
is assigned to the lower current value (4 mA).
4 Select the "Set URV" parameter.
Menu path: Setup → Extended setup → Current
output → Set URV
Enter the value for the "Set URV" parameter,
here 300 mbar (4.5 psi), and confirm. This
pressure value is assigned to the upper current
value (20 mA).
5 Result:
The measuring range is configured for
0 to +300 mbar (0 to 4.5 psi).
9.10 Configuring level measurement
9.10.1 Information on level measurement
You have a choice of two methods for calculating the level: "In pressure" and "In
height". The table in the "Overview of level measurement" section that follows
provides you with an overview of these two measuring tasks.
• The limit values are not checked, i.e. the values entered must be appropriate for the
sensor module and the measuring task for the device to be able to measure
correctly.
• Customer-specific units are not possible.
• The values entered for "Empty calib./Full calib.", "Empty pressure/Full pressure",
"Empty height/Full height" and "Set LRV/Set URV" must be at least 1% apart. The
value will be rejected, and a warning message displayed, if the values are too close
together.
