#### Contact Probe Offset

Calibrating the Contact probe offset using the same tool that was used to calibrate your Vision probe establishes a common offset frame of reference.

To calibrate the Contact probe offset:

1. Select the Insert | Hardware Definition | Probe menu item.

2. Define the contact probe and tip in the Probe Utilities dialog box.

3. Select Measure. to open the Measure Probe dialog box.

4. Specify the following values in the Measure Probe dialog box:

   - Motion: Man+DCC

   - Type of Operation: Calibrate Tips

   - Calibration Mode: User Defined

   - Start Angle: 0

   - End Angle: 359

   - List of Available Tools: 20mm Ring (Select the same tool as was used for determining the Vision probe offset)

5. Select Measure. When asked if the tool has moved, click No this time. This tells PC-DMIS that it does know the actual tool location on the stage.

6. Click OK on the tip reminder message box.

7. A message box will prompt you to take 1 hit on the tool face below or in the –Y direction from the bore center. Select OK and then take the contact point. The calibration routine will then do a course bore measurement, a face plane measurement, a more precise bore measurement, and then Z offset point measurements.

Now both probes have measured the tool and have offset values based on the same tool position data.
