Alert num-
ber
Alert title Possible cause Recommended actions
A013 Zero Calibration
Failed: Unstable There was too much process insta-
bility during the calibration proce-
dure.
This alert will not clear until you cy-
cle power to the meter. • Remove or reduce sources of electro-
mechanical noise (e.g., pumps, vibra-
tion, pipe stress), cycle power to the
meter, then retry the procedure.
A014 Transmitter Failure Many possible causes.
This alert often occurs in conjunc-
tion with alerts A9 and A26. • 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.
• Contact customer support.
A016 Sensor Temperature
(RTD) Failure The value computed for the resist-
ance of the line RTD is outside lim-
its. • Check your process conditions against
the values reported by the device.
• 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.
A017 Sensor Case Tem-
perature (RTD) Fail-
ure The values computed for the resist-
ance of the meter and case RTDs
are outside limits. • 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.
A020 Calibration Factors
Missing Some calibration factors have not
been entered or are incorrect. • Verify all of the characterization or cali-
bration parameters. See the sensor tag
or the calibration sheet for your meter.
• Verify the setting of the Sensor Type pa-
rameter.
• If Sensor Type= Curved Tube , ensure that
no parameters specific to Straight Tube
have been set.
