How to detect an inflection point
The amount of change in the indicated value at
Detection Interval A (load A) and the amount of
change in the indicated value at Detection Interval B
(load B) are compared, and when Difference C
between these loads exceeds the Detection Load
Difference set value, point a is held as an inflection
point.
If there are two or more inflection points in the hold
section, the point with a larger amount of change is
held.
Normally A=B, but if A<B with a gradual inclination,
it becomes easy to detect the inflection point.
