Ensure that the measurement unit for the configured process variable has been set as
desired.
Procedure
Set
LRV
and
URV
as desired.
•
LRV
is the value of
mA Output Process Variable
represented by an output of 4 mA. The
default value for
LRV
depends on the setting of
mA Output Process Variable
.
•
URV
is the value of
mA Output Process Variable
represented by an output of 20 mA. The
default value for
URV
depends on the setting of
mA Output Process Variable
. Enter
URV
in
the measurement units that are configured for
mA Output Process Variable
.
Tip
For best performance:
•
Set
LRV
≥
LSL
(lower sensor limit).
•
Set
URV
≤
USL
(upper sensor limit).
•
Set these values so that the difference between
URV
and
LRV
is ≥
Min Span
(minimum span).
Defining
URV
and
LRV
within the recommended values for
Min Span
,
LSL
, and
USL
ensures that the
resolution of the mA output signal is within the range of the bit precision of the D/A converter.
Note
You can set
URV
below
LRV
. For example, you can set
URV
to
50
and
LRV
to
100
.
The mA output uses a range of 4–20 mA to represent
mA Output Process Variable
. Between
LRV
and
URV
, the mA output is linear with the process variable. If the process variable
drops below
LRV
or rises above
URV
, the transmitter posts an output saturation alert.

Overview
Added Damping
controls the amount of damping that will be applied to the mA output.
Damping is used to smooth out small, rapid fluctuations in process measurement.
Damping
Value
specifies the time period (in seconds) over which the transmitter will spread changes
in the process variable. At the end of the interval, the internal value will reflect 63% of the
change in the actual measured value.
