4.3 Transmitter calibration
4.3.1 Calibration overview
Complete configuration and calibration of the 3051S MultiVariable Transmitter involves the
following tasks:
Configure the output parameters
Basic setup screen (page 24)
Set Process Variable Units
Set Primary Variable
Rerange
Set Transfer Function (Direct Process Variable Feature Board only)
Set Damping
Calibrate the sensor (DP, P, and/or T)
For each sensor, perform:
Sensor Trim (page 12)
Zero or Lower Sensor Trim (page 13)
Calibrate the 4–20 mA output
4–20 mA Analog Trim (page 18); or
4–20 mA Scaled Output Trim (page 18)
Figure 4-1 summarizes the data flow for the 3051S MultiVariable. Data flows from left to right,
and a parameter change affects all values to the right of the changed parameter.
