Recommended actions
A008
Density Overrange
The line density is greater than
3 g/cm
3
(3000 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 two-phase flow. See
•
Check for foreign material in the proc-
ess gas or fluid, coating, or other proc-
ess problems.
•
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. See
and
•
Perform Known Density Verification.
•
Contact Micro Motion.
A009
Transmitter Initializ-
ing/Warming Up
Transmitter is in power-up mode.
•
Allow the meter to complete its power-
up sequence. The alert should clear au-
tomatically.
•
If other alerts are present, resolve those
alert conditions first. If the current alert
persists, continue with the recommen-
ded actions.
•
Verify that the transmitter is receiving
sufficient power.
-
If it is not, correct the problem and
cycle power to the meter.
-
If it is, this suggests that the trans-
mitter has an internal power issue.
Replace the transmitter.
A010
Calibration Failure
Many possible causes.
This alert will not clear until you cy-
cle power to the meter.
•
Ensure that your calibration procedure
meets the documented requirements,
cycle power to the meter, then retry the
procedure.
•
If this alert appears during zeroing, veri-
fy that there is no flow through the sen-
sor, cycle power to the meter, then re-
try the procedure.
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.
