Result
● The selected pressure unit and pressure reference are displayed as alternating values in
the measurement view.
● If the converted pressure measurement has more than 5 digits, "#####" appears in the
measurement view.
9.2.2
Set lower range value [02]/Set upper range value [03]
9.2.2.1
Set lower range value parameter [02]
Sets the lower range value without applied pressure.
Setting range:
Within the measuring limits
Factory setting:
0 bar, or as specified in order
9.2.2.2
Set upper range value parameter [03]
Sets the upper range value without applied pressure.
Setting range:
Within the measuring limits
Factory setting:
Upper measuring range limit, or as specified in order
9.2.2.3
Set lower range value/upper range value (without pressure available)
Introduction
The lower range value (4 mA) corresponds to 0% of the measuring range. The upper range
value (20 mA) corresponds to 100% of the measuring range.
Without pressure available, you have the following options for assigning the desired pressure
measurements to the lower range value and the upper range value:
Device without display
Device with display
Remote operation
Set lower range value
-
"Lower range value" pa‐

The minimum permissible measuring span of the measuring cell must not be fallen below. You
can find the minimum permissible measuring span of your measuring cell in the section
