Possible cause
Recommended actions
A004
Temperature Over-
range
The RTD resistance is out of range
for the sensor. The tube RTD resist-
ance is out of range for the sensor.
•
Check your process conditions against
the values reported by the device.
•
Verify temperature characterization or
calibration parameters.
•
Verify that internal wiring is secure and
that there are no internal electrical
problems.
•
Check the wiring between the sensor
and the transmitter.
•
Contact customer support.
A005
Mass Flow Rate
Overrange
The measured flow rate is greater
than the maximum flow rate of the
sensor (
Δ
T greater than 200 µs).
•
If other alerts are present, resolve those
alert conditions first. If the current alert
persists, continue with the recommen-
ded actions.
•
Check your process conditions against
the values reported by the device.
•
Check for two-phase flow.
A006
Characterization Re-
quired
Calibration factors have not been
entered, or the sensor type is incor-
rect, or the calibration factors are
incorrect for the sensor type.
•
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.
•
Verify that internal wiring is secure and
that there are no internal electrical
problems.
•
Replace the core processor.
•
Contact customer support.
A008
Density Overrange
The line density is greater than
10 g/cm
3
(10000 kg/m
3
).
•
If other alerts are present, resolve those
alert conditions first. If the current alert
persists, continue with the recommen-
ded actions.
•
Check for air in the flow tubes, tubes
not filled, foreign material in the tubes,
coating in the tubes, or other process
problems.
•
Check for two-phase flow.
•
Verify all of the characterization or cali-
bration parameters. See the sensor tag
or the calibration sheet for your meter.
•
Check the drive gain and the pickoff
voltage.
•
Perform density calibration.
•
Contact customer support.
