Factory setting
Lower range value output In Current span parameter
(→  93), one of the
following options is selected:
• 4...20 mA NE (3.8...20.5
mA)
• 4...20 mA US (3.9...20.8
mA)
• 4...20 mA (4...20.5 mA)
• 0...20 mA (0...20.5 mA)
Enter lower range value for the
measured value range.
Signed floating-point
number
Depends on country:
• m³/h
• ft³/h
Upper range value output In Current span parameter
(→  93), one of the
following options is selected:
• 4...20 mA NE (3.8...20.5
mA)
• 4...20 mA US (3.9...20.8
mA)
• 4...20 mA (4...20.5 mA)
• 0...20 mA (0...20.5 mA)
Enter upper range value for
the measured value range.
Signed floating-point
number
Depends on country
and nominal
diameter
Fixed current The Fixed current option is
selected in the Current span
parameter (→  93).
Defines the fixed output
current.
0 to 22.5 mA 22.5 mA
Damping current output A process variable is selected
in the Assign current output
parameter (→  93) and one
of the following options is
selected in the Current span
parameter (→  93):
• 4...20 mA NE (3.8...20.5
mA)
• 4...20 mA US (3.9...20.8
mA)
• 4...20 mA (4...20.5 mA)
• 0...20 mA (0...20.5 mA)
Enter time constant for output
damping (PT1 element).
Damping reduces the effect of
fluctuations in the measured
value on the output signal.
0.0 to 999.9 s –
Failure behavior current output A process variable is selected
in the Assign current output
parameter (→  93) and one
of the following options is
selected in the Current span
parameter (→  93):
• 4...20 mA NE (3.8...20.5
mA)
• 4...20 mA US (3.9...20.8
mA)
• 4...20 mA (4...20.5 mA)
• 0...20 mA (0...20.5 mA)
Select output behavior in the
event of a device alarm.
• Min.
• Max.
• Last valid value
• Actual value
• Fixed value
–
Failure current The Defined value option is
selected in the Failure mode
parameter.
Enter current output value in
alarm condition.
0 to 22.5 mA –
