When you measure with an arm machine, it is recommended to hold it such that the probe is between your fingers with the buttons accessible with your thumb.
PC-DMIS Portable supports a variety of hard probes. The use and calibration of hard probes is similar to that of TTP probes.
If you selected a hard probe, PC-DMIS expects a probe that does not automatically trigger when it comes in contact with the part. DCC calibration cannot be done using a hard probe. Verify that you have selected the correct probe type.

When you measure with an arm machine, it is recommended to hold it such that the probe is between your fingers with the buttons accessible with your thumb. |
When you measure geometric features (lines, circles, planes, and other features) the probe radius is compensated based on the resolved feature itself rather than the individually compensated points.
Suppose you measure a plane. You do not need to measure the individual hit points that comprise the plane feature with the probe shaft perpendicular to the surface of the feature. |

PC-DMIS Portable monitors the probe shaft of the FIRST HIT when you measure a circle, cone, or cylinder to determine if you are measuring the inside diameter (ID) of the outside diameter (OD).
In most cases, you cannot physically orient the probe exactly normal to the surface of an ID circle without interference from the other side of the circle feature. The probe should be tipped as much as possible toward the center of the circle to register an inside diameter circle and away from the center to register an outside diameter circle.
After measurement of an ID or OD circle, you can verify that PC-DMIS has correctly determined the circle type by pressing F9 on the highlight feature in the Edit window. Check the Circular Feature Type option.
