h. Choose End.
Postrequisites
•
If the mA Output readings are within 20 microamps of the expected values, you can
correct this discrepancy by trimming the output.
•
If the discrepancy between the mA Output readings is greater than 20 microamps,
or if at any step the reading was faulty, verify the wiring between the transmitter
and the remote device, and try again.
•
If the Discrete Output readings are reversed, check the setting of Discrete Output
Polarity.
12.15
Trim mA output
Trimming an mA output calibrates the transmitter's mA output to the receiving device. If
the current trim value is inaccurate, the transmitter will under-compensate or over-
compensate the output.
12.15.1
Trim mA output using ProLink III
Trimming the mA output establishes a common measurement range between the
transmitter and the device that receives the mA output.
Important
You must trim the output at both ends (4 mA and 20 mA to ensure that it is compensated accurately
across the entire output range.
Prerequisites
Ensure that the mA output is wired to the receiving device that will be used in production.
Procedure
1.
Choose Device Tools > Calibration > MA Output Trim > mA Output 1 Trim.
2.
Choose Device Tools > Calibration > MA Output Trim > mA Output 1 Trim or Device
Tools > Calibration > MA Output Trim > mA Output 2 Trim.
3.
Follow the instructions in the guided method.
4.
Check the trim results. If any trim result is less than
−
20 microamps or greater than
+20 microamps, contact customer service.
12.15.2
Trim mA outputs using the Field Communicator
Trimming the mA output establishes a common measurement range between the
transmitter and the device that receives the mA output.
