3.2 Measurement

3.2.1 Dimensional measurement

Align a measuring point on the workpiece with one of the cross-hairs and take the reading from the

Micrometer Head. Then, move the XY stage by turning the Micrometer Head and align another

measuring point with the same cross-hair and take the reading at this point. The difference between

the two readings represents the dimension between the two measuring points.

A Digimatic Head and Digital Counter can be used, in place of the Micrometer Head, for digital

display of the displacement. They also eliminate reading errors. Since the zero-set button zeroes the

counter at any position, the displacement can be read directly.
