Figure 26 Evaluation of a break point
EP criterion
Measure of the minimum sharpness of the break point. The smaller the EP
criterion set, the more break points will be found. As this is a relative value
related to the total measured value modification, even small changes in
the measured value can be evaluated as a break point for a small mea-
sured value range.
Input range 0.0 - 1.0
Default value 0.3
Slope
Minimum difference between the slope before and after the break point.
The smaller the difference, the more break points will be found.
Input range 0.0 - 10.0
Default value 0.9
Smoothing factor
The higher the smoothing factor, the fewer break points will be found.
Input range 2 - 20
Default value 5
Set windows
This parameter allows to evaluate break points only in a certain range (so-
called window) of the curve. Break points outside this window will not be
evaluated. Only one window can be defined. Within this window how-
ever, all break points are evaluated.
