Possible causes
Transmitter is in power-up
mode.
If this occurs after device
startup, measurement sta-
bility has dropped below ac-
ceptable limits and the de-
vice is repeating its startup
sequence.
Many possible causes.
This alert will not clear until
you correct the problem,
acknowledge the alert, and
repeat the calibration.
Many possible causes.
The value computed for the
resistance of the line RTD is
outside limits.
Some calibration factors
have not been entered or
are incorrect.
The configured board type
does not match the physical
board.
This can indicate a loss of
communication between
the transmitter and the dis-
play module.

Recommended actions
• Allow the meter to complete its power-up se-
quence. The alert should clear automatically.
• If other alerts are present, resolve those alert con-
ditions first. If the current alert persists, continue
with the recommended actions.
• Verify that the transmitter is receiving sufficient
power.
- If it is not, correct the problem and cycle pow-
er to the meter.
- If it is, this suggests that the transmitter has an
internal power issue. Replace the transmitter.
• Ensure that the process fluid is stable. Check for
two-phase flow, high process noise, or a fast tran-
sition between two fluids of different densities.
• Ensure that your calibration procedure meets the
documented requirements, cycle power to the
meter, then retry the procedure.
• Ensure that all wiring compartment covers are in-
stalled correctly.
• Ensure that all transmitter wiring meets specifica-
tions and that all cable shields are properly termi-
nated.
• Check the grounding of all components. See
Section 10.3.
• Evaluate the environment for sources of high elec-
tromagnetic interference (EMI) and relocate the
transmitter or wiring as necessary.
• Contact Micro Motion.
• Check your process against the values reported by
the device.
• Contact Micro Motion.
• Verify all of the characterization or calibration pa-
rameters. See the sensor tag or the calibration
sheet for your meter.

rameters. See the sensor tag or the calibration
sheet for your meter.
• Ensure that the correct board is installed.
• Cycle power to the meter.
• Replace the display module.
