#### To Define the Probe Configuration for Each Slot

1. Select the appropriate probe changer from the Active Probe Changer list.

2. Click the plus sign (+) to the left of the slot number. You'll notice that PC-DMIS displays a "no probe" item as the default.

3. Double-click or right-click on the "no probe" item. A list will appear.

4. Assign the appropriate probe file or extension to each slot.

5. Select the slot number, and then click the Edit Slot Data button. The Probe Changer Slot Data dialog box appears. See "To Manually Edit a Slot's Data".

6. From the Slot Type list, specify what type of hardware the slot will hold. Select either Probe Attached if it will hold a probe or Extension Only if you only want it to hold a probe extension. If the slot is empty, select Undefined. On some probe changers you can select specific inserts from this list.

7. Define the XYZ location for the slot by typing in the X, Y, and Z values for the Slot Number.

8. If using an ACR1 or TESASTAR-R probe changer and you have defined the slot type as Extension Only, set the value for the Rotation Angle of Bottom Joint (degrees) box. If desired, you can also define the XYZ location of the bottom of the extension by defining the X,Y, and Z boxes in the With Empty Extension area.

9. Define the Before drop-off and Before pick-up clearance distance values as desired. See "About Slot Clearance Distances" for more information.

10. Click OK to accept your changes.

11. Each probe configuration must be loaded into the rack using the CMM Arm and Load Active Probe option. (Do not insert the probe into the rack by hand.)

Note: Extensions are not manufactured within the necessary tolerances to be interchangeable without recalibration. Therefore, if you have already configured a slot for a specific extension, and you want that slot to hold a different extension (even an extension of the same size), you will need to recalibrate the slot for the new extension.
