Problem:
This message indicates a special input error.
Cause:
The special input exceeds the specified limits for the analog inputs, or no input device is connected.
Action:
Check the input device and the connecting cable. Recalibrate the analog input.
9.2.17 E21: API Error
Problem:
This message indicates an error in the API calculations.
Cause:
The combination of pressure, temperature, density, and/or flow inputs causes the calculation to not
properly resolve.
Action:
The specific API error can be found in the API Info section of the meter's program.
9.2.18 E22: Degraded Performance Error
Problem:
The accuracy of the measurement is degraded.
Cause:
A loss of one inner and/or outer chord measurement results in the sister inner/outer chord's
measurement to be substituted, to provide a flow measurement with degraded accuracy.
Action:
Consult the factory.
