8.3.2 Configure Lower Range Value (LRV) and Upper Range Value
(URV) for the mA Input
Display Menu > Configuration > Inputs/Outputs > Channel D > I/O Settings > Lower Range Value
Menu > Configuration > Inputs/Outputs > Channel D > I/O Settings > Upper Range Value
ProLink III Device Tools > I/O > Inputs > mA Input > Range Values
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel D > mA Input > LRV
Configure > Manual Setup > Inputs/Outputs > Channel D > mA Input > URV
The Lower Range Value (LRV) and Upper Range Value (URV) are used to scale the mA Input, that is, to define
the relationship between the external variable and the mA Input signal.
LRV is the value of mA Input Assignment represented by an input of 4 mA. URV is the value of mA Input
Assignment represented by an input of 20 mA. Between LRV and URV, the mA Input is linear with the process
variable. If the process variable drops below 3.8 mA or rises above 20.5 mA, the transmitter posts an input
failure alert.
Procedure
Set LRV and URV as desired.
Enter LRV and URV in the measurement units that are appropriate for mA Input Assignment.
• Defaults: 0
• Range (in default measurement units):
— Pressure: 0 PSI to 1000 PSI
— Temperature: 0 °C to 250 °C
— Loop current: 4 mA to 20 mA
Note
You can set URV below LRV. For example, you can set URV to 50 and LRV to 100 . If you do this, the mA Input
will be inversely proportional to the value of mA Input Assignment

8.3.3 Configure mA Input Damping

Display Menu > Configuration > Inputs/Outputs > Channel D > I/O Settings > Damping
ProLink III Device Tools > Configuration > I/O > Inputs > mA Input > mA Input Damping
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel D > mA Input > Damping
mA Input Damping controls the amount of damping that will be applied to the mA Input.
Damping is used to smooth out small, rapid fluctuations in process measurement. The 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 transmitter's internal value will reflect 63% of the change in the actual value
sent by the external device.
mA Input Damping affects a process variable only when it is received via the mA Input. If the process variable
is read digitally, mA Input Damping is not applied.
