Alert num-
ber
Alert title Possible cause Recommended actions
A011 Zero Calibration
Failed: Low Many possible causes, such as too
much flow, especially reverse flow,
through the sensor during a calibra-
tion procedure, or a zero result that
is too low. This alert is accompanied
by A010.
This alert will not clear until you cy-
cle power to the meter. • Verify that there is no flow through the
sensor, cycle power to the meter, then
retry the procedure.
A012 Zero Calibration
Failed: High Many possible causes, such as too
much flow, especially forward flow,
through the sensor during a calibra-
tion procedure, or a zero result that
is too high. This alert is accompa-
nied by A010.
This alert will not clear until you cy-
cle power to the meter. • Verify that there is no flow through the
sensor, cycle power to the meter, then
retry the procedure.
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. • 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 Micro Motion.
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 Micro Motion.
