Maximal hold
Detect and hold maximal value. Maximal value is updated every detection and final maximal value is hold when
section finished.
If plus/minus over occurs, maximal value is not detected.
When recovering from plus over or minus over, the maximal value is updated by the value after returning.
Maximal value detection is performed by sequentially detecting the maximum value and the minimum value as in
the following procedure and hold at the timing of the minimum value detection.
①
Maximum value detection
The maximum value is temporarily placed as a local maximal value when (maximum value - current value) >
difference value of maximum and minimum values.
②
Minimum value detection
The minimum value is taken as a minimal value when (current value - minimum value) > (maximal value -
minimum value) × difference magnification, and hold the maximal value.
You need to set defference value (DifValue) and difference magnification (DifMag).
