A009 Transmitter
Initializing/Warming
Up Transmitter in power-up
mode. • Allow the flowmeter to warm up (approximately 30
seconds). The error should disappear once the
flowmeter is ready for normal operation.
• If alarm does not clear, make sure that the sensor is
completely full or completely empty.
• Check the sensor circuitry. See Section 11.25.

many possible causes.
• If alarm appears during a transmitter zero, ensure
that there is no flow through the sensor, then retry.
• Cycle power to the flowmeter, then retry.
• If appropriate, restore the factory zero to return the
flowmeter to operation.
Calibration Failure
A011 Excess Calibration
Correction, Zero
too Low See A10 • Ensure that there is no flow through the sensor, then
retry.
• Cycle power to the flowmeter, then retry.
• If appropriate, restore the factory zero to return the
flowmeter to operation.
Zero Too Low
A012 Excess Calibration
Correction, Zero
too High See A10 • Ensure that there is no flow through the sensor, then
retry.
• Cycle power to the flowmeter, then retry.
• If appropriate, restore the factory zero to return the
flowmeter to operation.
Zero Too High
A013 Process too Noisy
to Perform Auto
Zero See A10. • Remove or reduce sources of electromechanical
noise, then retry. Sources of noise include:
- Mechanical pumps
- Pipe stress at sensor
- Electrical interference
- Vibration effects from nearby machinery
• Cycle power to the flowmeter, then retry.
• If appropriate, restore the factory zero to return the
flowmeter to operation.
Zero Too Noisy
A014 Transmitter Failed Many possible causes. • Cycle power to the flowmeter.
• The transmitter might need service. Contact Micro
Motion. See Section 11.3.

A016 Line RTD
Temperature
Out-Of-Range The value computed for
the resistance of the Line
RTD is outside limits • Check the sensor RTD circuitry. See Section 11.25.
• Verify that process temperature is within range of
sensor and transmitter.
• If the problem persists, contact Micro Motion. See
Section 11.3.

A017 Meter RTD
Temperature
Out-Of-Range The value computed for
the resistance of the
Meter/Case RTD is
outside limits • Check the sensor RTD circuitry. See Section 11.25.
• Verify that process temperature is within range of
sensor and transmitter.
• If the problem persists, contact Micro Motion. See
Section 11.3.
• Check the characterization. Specifically, verify the
FCF and K1 values. See Section 6.2.
