Overview

This section contains information on commissioning and operating 3051 Wireless Pressure
Transmitters.
Field Communicator and AMS instructions are given to perform configuration functions. For
convenience, Field Communicator fast key sequences are labeled "Fast Keys" for each software
function below the appropriate headings.

Calibration

Calibrating a 3051 Wireless transmitter may include the following procedures:

The 3051 sensor module uses a microprocessor that contains information about the sensor's
specific characteristics in response to pressure and temperature inputs. A smart transmitter
compensates for these sensor variations. The process of generating the sensor performance
profile is called factory sensor characterization.
Sensor trimming requires an accurate pressure input and adds additional compensation that
adjusts the position of the factory sensor characterization curve to optimize performance over a
specific pressure range.
Note
Sensor trimming adjusts the position of the factory sensor characterization curve. It is possible
to degrade performance of the transmitter if the trim is done improperly or with inaccurate
equipment.
Operation and Maintenance
Operation and Maintenance
Sensor Trim: Adjusts the position of the factory sensor characterization curve to
optimize performance over a specified pressure range, or to adjust for mounting
effects.
