#### Step 7: Calibrating the NC-100 Artifact

In this step PC-DMIS will calibrate the polyhedral tool by measuring each hole on each face of the polyhedral tool.

1. Click the Measure button from the Probe Utilities dialog box. The Measure Probe dialog box appears.

2. Ensure that the Number of Hits box has the value of 4 or higher. This number indicates the number of hits taken to measure each hole on the faces of the tool.

3. Select the DCC option button.

4. Select the Calibrate NC-100 Artifact option button from the Type of Operation area

5. Select the polyhedral tool from the List of Available Tools list.

6. Click the Measure button. PC-DMIS displays two message boxes at this point. The first asks if you would like to establish the initial orientation.

7. Click NO. You already performed this step earlier. The second message box asks if the qualification tool has been moved.

8. Since you haven't calibrated the polyhedral tool yet, click YES. PC-DMIS now asks you if the CMM is ready to rotate the probe head.

9. Click OK. The Execution Mode Options dialog box appears and PC-DMIS will begin the measurement process. You will measure the very first face of the tool manually. PC-DMIS will prompt you to first take three sample hits.

10. Take the three sample hits on the face most normal to the shank vector (the very top of the tool). PC-DMIS will then prompt you to take hits inside the hole (based on the number of hits you specified earlier).

11. Take the hits inside the hole. After you measure the first face manually, PC-DMIS will take over and measure the remaining faces in DCC mode.

When PC-DMIS finishes measuring all 17 faces of the polyhedral tool, it will display the Probe Utilities dialog box again.

You have now completed the first half—and most complex part—of the video probe calibration process. The rest of the process is less tedious and should only take a few more minutes.
