2.4 Trim the transmitter
Devices are calibrated by the factory. Once installed, it is recommended to
perform a zero trim on gage and differential pressure transmitters to
eliminate error due to mounting position or static pressure effects. A zero
trim can be performed using either a Field Communicator or configuration
buttons.
For instructions using AMS Wireless Configurator, see the Rosemount 3051

Note
When performing a zero trim, ensure the equalization valve is open and all
wet legs are filled to the correct level.
CAUTION
It is not recommended to zero an absolute transmitter, Rosemount 3051CA
or 3051TA models.
