#### PrbRdv

The PrbRdv box on the Edit Probe Data dialog box allows you to set a radial deviation for the calibrated size of the tip.

When you execute the probe calibration, PC-DMIS does one of two things:

1. If you have a machine configuration where PrbRdv applies, the calibration process automatically sets the tip size to the theoretical value, calculates, and then saves a PrbRdv value.

2. If you have a machine where PrbRdv does not apply, the calibration automatically sets the PrbRdv value to zero, calculates, and then saves a tip size slightly different from the theoretical value.

The Edit Probe Data dialog box merely allows you to edit the tip size and/or PrbRdv if needed for some reason after calibration. If you re-calibrate, the resulting values will come from the calibration, not from whatever may have been manually entered into this dialog box prior to calibrating.

Note: This box is only available for selection if you use an analog probe on certain machines.
