2-wire RTD offset
The 2-wire Offset feature allows the measured lead wire resistance to be input and corrected for, which
results in the transmitter adjusting its temperature measurement for the error caused by this added
resistance. Because of a lack of lead wire compensation within the RTD, temperature measurements
made with a 2-wire RTD are often inaccurate.
This feature can be configured as a subset of the Sensor Configuration process in the Field
Communicator, AMS Device Manager, and the Local Operator Interface.
To utilize this feature properly perform the following steps:
