Calibration

4.2.1 Calibration overview
Calibrating a Rosemount ERS System involves the following tasks:
Procedure
1. Configure process variables.
2. Calibrate the P
3. Zero trim the differential pressure.
4. Calibrate the 4–20 mA output.

See Basic setup for additional details on configuring the following:
• Units of measure
• Damping

Calibrate each pressure sensor by performing a zero/lower and an upper sensor
trim.
Perform a zero-trim on the Differential Pressure (DP) reading to establish a zero-
based measurement.
Adjust the analog output to match the control loop.
