Determining a Value at a Specific Operating Point

Performing a tradeoff calibration necessarily involves the comparison of two or more models.

For example, in this case, the calibrator uses his or her judgment to select a value of spark that gives acceptable values for both the torque and the NOx flow models.

To select a value of spark, do one of the following:

• Click the edit box as shown above and enter the required value.
• Drag the red line.

Once you determine the value of your variable at this operating point, you apply this value to the table by pressing Ctrl+T, by selecting Table -> Apply Point, or by clicking  (Add Point) in the toolbar.
