Procedure
1. Select Piece-wise linear from the Calibration|Meter Factors menu.
2. Click the Add button below the table to add a new calibration point to the bottom of
the table. You can add a maximum of 12 points. The calibration points must be
entered from the highest flow rate to the lowest flow rate.
3. Click Write to apply the calibration parameters to the meter.
Wet calibration third-order polynomial
When the Polynomial wet calibration method is selected, the meter uses a third-order
polynomial on the dry-calibration velocity Equation 5-4.
