The measure options allow you to select what method PC-DMIS will use to perform the translation comparison.
The Measure 3 Spheres option tells PC-DMIS to use spheres as the features for translation comparison. This method uses the center of each measured sphere.
The Measure 3 Point Sets option tells PC-DMIS to use the centroid of a set of points. It is recommended that you use the bottom of an inverted cone with a hard probe. This method is slightly more accurate than the spheres method and much quicker for the operator.
The Measure 3 Points option tells PC-DMIS to use only three points and is the least accurate of the three methods.
The Measure Datums option tells PC-DMIS to use existing datum features from a measurement routine of your choice. Because the datum features are already assumed to have been measured in your existing measurement routine, you only need to measure them after relocating your machine.
