5.1 Overview
This section contains information on commissioning and operating 2051 Wireless Pressure
Transmitter s.
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.
5.2 Safety messages
Instructions and procedures in this section may require special precautions to ensure the safety
of the personnel performing the operations. Information that potentially raises safety issues is
indicated by a warning symbol ( ). Please refer to the following safety messages before
performing an operation preceded by this symbol.
5.3 Calibration overview
Calibrating a 2051 Wireless transmitter may include the following procedures:
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.
The Rosemount 2051 sensor module contains information about the sensor’s specific charac-
teristics 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.
