Custom Characterization Dialog Box
Use the Characterization dialog box (Figure 83) to define characterizations. There are
nine definable points for the valve position at 10% increments of position Set Point. Use
the mouse to drag the points on the curve or enter numerical values in the table to
define the characterization.
Figure 83 Custom Characterization Dialog Box
To configure a custom characteristic curve:
1. Enter the values in the edit boxes or mouse drag a point. The graph updates when
the value is entered.
2. Click OK to accept the value and exit the Custom Characterization dialog box.
ValVueFF checks the curve based on established rules. A warning appears if the
curve does not meet the rules. The characteristic points are saved in FVP with a
resolution of five digits.
The unfinished curve in Figure 83 illustrates that the curve must be monotonic.
Each point must be greater than the previous point.
To smoothly blend a point between its adjacent points:
❑ Right-click the point.
The curve in Figure 83 results in the display shown in Figure 84.
