• If other alarms are present (typically, A003, A006, A102, or 

A105), resolve those alarm conditions first. If the A008 
alarm persists, continue with the suggestions here.

• Verify process. Check for air in the flow tubes, tubes not 

filled, foreign material in tubes, or coating in tubes.

• Check for slug flow. See Section 10.17.
• Check the sensor circuitry. See Section 10.24. 
• Verify calibration factors in transmitter configuration. See 

• Check the test points. See Section 10.23.
• If the problem persists, contact Micro Motion.

Density Overrange

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 10.24.

Calibration Failure

Mechanical zero: The 
resulting zero was greater 
than 3 

μs.

Temperature/Density Cals: 
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. 

Transmitter Failed

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 10.24.
• Verify that process temperature is within range of sensor 

and transmitter.

• If the problem persists, contact Micro Motion.

Calibration Factors 
Unentered

The flow calibration factor 
and/or K1 has not been 
entered since the last 
master reset.

• Check the characterization. Specifically, verify the FCF 

and K1 values. See Section 4.2.

• If the problem persists, contact Micro Motion.
