Procedure
1. Select Polynomial from the Calibration|Meter Factors menu.
2. Add the value for the forward and reverse coefficients.
3. Click Write to apply the parameters to the meter.
No wet calibration
If no wet calibration is selected, then the wet calibration gas flow velocity is equal to the
dry calibration gas flow velocity.
