Prerequisites
Ensure that mA Output Process Variable is set to the desired process variable. Each process
variable has its own set of LRV and URV values. When you change the values of LRV and
URV, you are configuring values for the currently assigned mA output process variable.
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.
