#### Step 5: Establishing the Orientation of the Polyhedral Calibration Tool

PC-DMIS will ask you to measure two planes on the polyhedral calibration tool. These planes will then be used to establish the orientation of the tool.

1. Click the Measure button in the Measure Probe dialog box. A message box appears and asks if you would like to establish the initial orientation.

2. Click YES. You should only click NO if you had previously established the orientation. Another message box appears asking if you want to move the PH9 /10 head.

3. Click YES. The Execute Mode dialog box appears. PC-DMIS asks you to take three hits to measure a plane.

4. Take the three hits on the face of the calibration tool that is most normal to the probe position of T1A0,B0,C0.

5. Press Done on your jog box. PC-DMIS then asks if you're ready to rotate the PH9/10 to the second position.

6. Click OK. PC-DMIS rotates the tip angle to the second tip angle of T1A90B180C0. Again, PC-DMIS asks you to take three hits to measure a plane.

7. Take three hits on the face of the calibration tool that is most normal to the current probe position.

8. Press Done on your jog box. After you press Done, PC-DMIS displays another message box, stating that not all of the tips required for calibration are available in the probe file.

9. Click YES to add these tip positions. PC-DMIS will then add up to 17 new positions will to the Active Tip List in the Probe Utilities dialog box.

Important: Do not move the polyhedral tool after establishing this initial orientation! Even though the sphere calibration tool is used in the next step, you will use the polyhedral tool again, and if you move the tool, you will need to begin the calibration process from the beginning.
