#### To Manually Edit a Slot's Data

1. Select the appropriate slot from the Active Probe Changer list.

2. Click the Edit Slot Data button. The Probe Changer Slot Data dialog box appears. For all probe changer types, the XYZ boxes should be available to edit. While you can use these boxes to manually enter a position if needed, these values are normally determined by measurements resulting from running the calibration procedure for the probe changer. You can use this dialog box to change a slot's type and XYZ location. For TESASTAR-R and Autochange(ACR1) probe changers, you can also use it to edit an extension's XYZ location and edit the rotation angle of the bottom joint.

3. Some probe changer types support multiple possible configurations for each slot. Some example probe changer types that allow this include the Autochange(ACR1) and TESASTAR-R.

- When using a changer with multiple possibilities for each slot, the Slot Type list will be active and filled with selections appropriate for that changer type.

- To specify the appropriate configuration, choose the appropriate entry from the list. For more in-depth information on the meaning of the selections available for a particular changer type, consult your hardware documentation for the probe changer.

- When slot type selections are available, you should set them before running the calibration procedure for the probe changer. Changing them later typically requires a re-calibration of the probe changer, or at least the individual slots that were changed.

4. Some probe changer types have slot types that let you use empty extensions that do not have actual probes attached. Some example probe changer types that allow this include the Autochange(ACR1) and the TESASTAR-R.

- When using a probe changer that supports empty extensions, and if you have defined a slot as Extension Only, the With Empty Extension and Rotation Angle Bottom Joint areas become active.

- While you can manually enter the XYZ location for the empty extension, this will normally be determined from calibrating the probe changer.

- Some extension bars have a bottom joint that is rotated by some amount relative to the top joint. If you use one of these extension bars, you must define the amount of rotation in the Rotation Angle of Bottom Joint box before calibrating the probe changer. Changing it later will require re-calibration of the probe changer, or at least the individual slots that were changed.

5. If desired, define separate Before drop-off and Before-pick up clearance distances in the Clearance Distances area. See "About Slot Clearance Distances" for more information

6. When you have finished specifying the desired values, click OK. PC-DMIS closes the dialog box and shows a summary of the specifications for that slot in the Probe Changer dialog box. If any values were changed, it will also indicate "changes pending" for the slot.

7. If you want to revert a slot to its previous value, you can select that slot, click the Edit Slot Data, and then from the Probe Changer Slot Data dialog box, click the Restore XYZ, Restore Type, or Restore Angle buttons as applicable. These buttons are only available for selection if changes have been made but you haven't yet clicked OK or Apply on the Probe Changer dialog box.

8. If you're ready to accept your changes, click either the OK or Apply button on the Probe Changer dialog box.
