Zero Trim
Note
The transmitter must be within three percent of the span away from zero (for zero-based
spans) in order to calibrate with zero trim function. If the zero reading is not within three
percent of the true zero, the transmitter will require iterative trims to move the zero within
trimmable range.
Field Communicator
Calibrate the sensor with a Field Communicator using the zero trim function as follows:
1.
Vent the transmitter and attach a Field Communicator to the measurement loop.
2.
From the

3.
Follow the commands provided by the Field Communicator to complete the zero
trim adjustment.
