To correctly calibrate your probe using a Faro arm, follow this procedure:
Access the Probe Calibration Utilities dialog box.
From the Calibration Method area, select the appropriate calibration method.
Select any useful check boxes.
Click the Measure button to begin the calibration process. PC-DMIS displays some visual aids to assist you in calibrating the Faro arm.
Follow any on-screen instructions (including instructions that may appear in the dialog box's status area).
If you’re using the one inch sphere method, take the following hits on the spherical tool, using this diagram and any on-screen aids to assist you:

A - West B - North pole (red line) C - East D - Equator of the spherical tool (blue line) E - Side view of Faro magnet showing spherical tool attached F - Side view of the part on the table G - Side view of the clamp attached to the table |
Take five hits around the equator.
Flip the last axis and take another five hits around the equator.
Take five hits normal to the sphere from east to west.
Flip the last axis and take four hits normal to the sphere from west to east.
Take four hits normal to the sphere from north to south.
Flip the last axis and take four hits normal to the sphere from south to north.
If you’re using the hole calibration technique, PC-DMIS asks you to take these hits:
Take 10 hits in the hole while rotating the handle.
Take 10 hits in the hole from the opposite direction.
Click OK when you finish calibrating.
