Calibration Tasks
NOTE:
A Field Communicator is required for all sensor and output trim procedures.
Rosemount 3051S_C Range 4 and Range 5 transmitters require a special
calibration procedure when used in differential pressure applications under
high static line pressure (see “Compensating for Line Pressure (Range 4 and
Range 5)” on page 4-10).
Rosemount 3051S_TG Range 5 transmitters use an absolute sensor that
requires an accurate absolute pressure source to perform the optional sensor
trim.
Calibration Overview
Complete calibration of the 3051S pressure transmitter involves the following
tasks:
Configure the analog output parameters
• Set Process Variable Units (page 3-8)
• Set Output Type (page 3-8)
• Rerange (page 3-9)
• Set Damping (page 3-11)

3051S_ TG, Range 5
1. Set output configuration parameters:
a. Set the range points.
b. Set the output units.
c. Set the output type.
d. Set the damping value.
2.
Optional
: Perform a sensor trim if
equipment available (accurate absolute

Optional
: Perform an analog output
trim (Accurate multimeter required)
1. Reconfigure parameters if necessary.
2. Perform low trim value section of the
sensor trim procedure to correct for
mounting position effects.
