### Step 1: Install and Launch PC-DMIS Vision

Before working with your optical measuring system, ensure that PC-DMIS Vision has been properly installed on your computer system.

To install PC-DMIS Vision:

1. Attach your portlock programmed with the Vision option to your computer. You must also have the correct Vision probe type from the Vision Type drop-down box programmed. The portlock settings must be selected prior to installing PC-DMIS to ensure that the needed Vision components will be installed. Please contact your PC-DMIS software distributor if your portlock has not been properly configured.

2. Install PC-DMIS. During the initial PC-DMIS install process, you will be prompted to install Frame Grabber software. See the "Frame Grabber" topic for more information.

3. Verify that specific calibration tests have been completed for your Vision machine. These tests should already have been completed by a trained technician. You can verify that your machine is ready by confirming the following files reside on your computer system located in the root directory where you installed PC-DMIS:

- *.ilc: Files that have an .ilc extension are created during the calibration process of your machine's lamps. They store the illumination calibration data for each lamp and optics lens combination.

- *.ocf, *.mcf and *.fvc: These files are created during the calibration of your machine’s optics. They store the calibration data needed to map pixel size to real world units and correct for optical parcentrality/parfocality errors.

- Comp.dat: This file is created during the calibration of your machine’s stage, storing the calibrations for position on the X, Y and Z axis.

These calibration files may or may not exist and are not prerequisite to running PC-DMIS Vision. If this is a new install, then the files will not exist. As calibrations are executed inside of PC-DMIS, these files will be created.

CAUTION: Do not, under any circumstances, alter these files. A trained service technician must make any calibration adjustments to these areas of the system.

4. Start PC-DMIS in online mode by selecting Start | (All) Programs | PC-DMIS for Windows | Online.

5. Open an existing part program, or create a new one. If you create a new part program the Probe Utilities dialog box appears.
