Operation and Maintenance
To calibrate the sensor with a Field Communicator using the sensor trim function, perform the following
procedure:
1. Select 2: Lower Sensor Trim.
Note
Select pressure points so that lower and upper values are equal to or outside the expected process
operation range. This can be done by going to“Rerange the transmitter” on page 13 of Section 2.
2. Follow the commands provided by the Field Communicator to complete the adjustment of the lower
value.
3. Select 3: Upper Sensor Trim.
4. Follow the commands provided by the Field Communicator to complete the adjustment of the upper
value.
AMS Device Manager
Right click the device and, under the Method drop down menu, move cursor over Calibrate and, under
Sensor Trim, select Lower Sensor Trim.
1. Follow the screen prompts to perform a Sensor Trim using AMS Device Manager.
2. If desired, right click the device and under the Method drop down menu, move cursor over Calibrate
and under Sensor Trim and select Upper Sensor Trim.
LOI
Perform an upper and lower Sensor trim by referencing Figure 5-3.

Performing a digital zero trim (option DZ)
A digital zero trim (option DZ) provides the same function as a zero/lower sensor trim, but can be
completed in hazardous areas at any given time by simply pushing the zero trim button when the
transmitter is at zero pressure. If the transmitter is not close enough to zero when the button is pushed,
the command may fail due to excess correction. If ordered, a digital zero trim can be performed by
utilizing external configuration buttons located underneath the top tag of the transmitter, see Figure
5-1 on page 47 for DZ button location.
