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.
