This list is available only on the Square Slot auto feature.
When you select Yes from Meas Width and then click the Create button, PC-DMIS will do the following during measurement:
Measure two hits on the side of the slot.
Adjust the angle vector.
Measure two hits on the opposite side to calculate the width.
Adjust the position of the last two hits at each end for the width.
Generally, Square Slots only require five hits. With this option, however, taking six hits will yield a better measurement of the width.
