Operation and Maintenance

5.4.1

Recall factory trim—sensor trim

The Recall Factory Trim—Sensor Trim feature allows the restoration of the as-shipped factory 
settings of the analog output trim. This command can be useful for recovering from an 
inadvertent trim, incorrect Plant Standard or faulty meter.

Recall factory trim – sensor, using a Field Communicator

From the 

HOME

 screen, enter the Fast Key sequence and follow the steps within the Field 

Communicator to complete the Sensor Trim.

5.4.2

Active calibrator and EMF compensation

The transmitter operates with a pulsating sensor current to allow EMF compensation and 
detection of open sensor conditions. Because some calibration equipment requires a steady 
sensor current to function properly, the “Active Calibrator Mode” feature should be used when 
an Active Calibrator is connected. Enabling this mode temporarily sets the transmitter to 
provide steady sensor current unless two sensor inputs are configured.

Disable this mode before putting the transmitter back into the process to set the transmitter 
back to pulsating current. “Active Calibrator Mode” is volatile and will automatically be disabled 
when a master reset is performed (through HART) or when the power is cycled.
