## Step 5: Calibrate Probes

In order to create alignments or measure your gear, you must first calibrate your probe.

To calibrate your probe:

1. Select the Measure | Probe Calibration menu option...

... or the Probe toolbar icon...

... to launch PC-DMIS in the background and use a Save As dialog box to navigate to a desired probe file.

2. Browse to and select an existing probe file (*.prb) or type the File name to define a new probe file. When you click Save, PC-DMIS Gear will open the PC-DMIS Probe Utilities dialog box.

3. From the Probe Utilities dialog box you can then define and then use the Measure... button to calibrate your probe. If needed, see the core PC-DMIS help file for information on calibrating probes.

4. Click OK when you have finished the probe calibration.
