Recommended actions
•
Check your process conditions against
the values reported by the device. Tem-
perature should be between –200 °F
and +400 °F.
•
Verify all of the characterization or cali-
bration parameters. See the sensor tag
or the calibration sheet for your meter.
•
Check the wiring between the sensor
and the transmitter.
•
Verify that internal wiring is secure and
that there are no internal electrical
problems.
•
Contact customer support.
•
Ensure that all wiring compartment
covers are installed correctly.
•
Ensure that all transmitter wiring meets
specifications and that all cable shields
are properly terminated.
•
Check the grounding of all compo-
nents.
•
Evaluate the environment for sources of
high electromagnetic interference
(EMI) and relocate the transmitter or
wiring as necessary.
•
Cycle power to the meter.
•
If the alert persists, replace the trans-
mitter.
