Overview
The Lower Range Value (LRV) and Upper Range Value (URV) are used to scale the readings
received from the external measurement device, i.e., to define the relationship between
mA input Process Variable and the mA input level received. Between LRV and URV, the mA
input is linear with the process variable. If the process variable drops below LRV or rises
above URV, the transmitter posts an external input error.
Prerequisites
Verify that you have set the measurement units for the pressure or temperature to match
the units configured at the external measurement device. For example, if the external
measurement device is set to send pressure data in PSI, you must set the pressure
measurement units to be PSI at your transmitter.
Procedure
1. Set LRV as desired.
Tip
Set the LRV to match the lower range value at the remote device.
2. Set URV as desired.
Tip
Set the URV to match the upper range value at the remote device.

Configure events
An event occurs when the real-time value of a user-specified process variable moves past a
user-defined setpoint. Events are used to provide notification of process changes or to
perform specific transmitter actions if a process change occurs.
Your transmitter supports two event models:
• Basic event model
• Enhanced event model
