Explanation of Functions Previous average value comparison Use the previous average value comparison to not detect gentle changes and only detect sudden changes. Off-center 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. Measurement Values Functions and Operations Measurements without using previous average value comparison Measurements using previous average value comparison 0 360° 5-41 Section 5 Functions and Operations Previous average value comparison makes the measurement value the difference between the present input value and the average of all previous input values.
