PC-DMIS must measure Auto Square slots at a 45 degree angle to the slot (see the illustrations below). Depending on the size of the slot, PC-DMIS takes one of these two paths.
Path 1: Small Slot - Measured with a single pass of the laser sensor
Small square slots require a single pass of the laser sensor’s stripe
(A) - Diagonal scan motion
Path 2: Large Slot - Measured with multiple passes of the laser sensor
Large square slots require multiple passes of the laser sensor's stripe
