5.11 Detecting Sudden Input Changes
"Previous average comparison" is a function that detects only sudden changes to input signals.
Use the previous average comparison to not detect gentle changes and only detect sudden changes.
As shown in the above diagram, when rotating a cylindrical object and measuring the distance from the
object using a laser displacement meter, it cannot be judged if the increase in measurement values when
the rotating axis is eccentric is due to the eccentricity or to a burr.
