Measuring the Plane Displacement (Plane
Scanning Measurement)
Moving the probe while maintaining contact with the surface of the workpiece obtains multiple
measurements. Based on the acquired data, the maximum, minimum, and displacement values
(maximum – minimum = displacement) can be measured.
As an example, the procedure for measuring the displacement of a1 (maximum value), a2 (minimum
value), and A (1 mm), shown below, is explained.
A (1 mm)
a2
a1
ABS origin
NOTE
Measure within a range of about 1 mm from the starting point. Measuring with a wider range may
increase measurement errors.
