Postrequisites
•
If the mA output reading was slightly off at the receiving device, you can correct this
discrepancy by trimming the output.
•
If the mA output reading was significantly off (±200 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 reading is reversed, check the setting of
Discrete Output Polarity
.

Check for radio frequency interference (RFI)
The transmitter's frequency output or discrete output can be affected by radio frequency
interference (RFI). Possible sources of RFI include a source of radio emissions, or a large
transformer, pump, or motor that can generate a strong electromagnetic field. Several
methods to reduce RFI are available. Use one or more of the following suggestions, as
appropriate to your installation.
Procedure
•
Eliminate the RFI source.
•
Move the transmitter.
•
Use shielded cable for the frequency output or discrete output.
-
Terminate the shielding at the output device. If this is impossible, terminate the
shielding at the cable gland or conduit fitting.
-
Do not terminate the shielding inside the wiring compartment.
-
360-degree termination of shielding is unnecessary.
