### Using the Calibration File

To use the calibration file, load it into the job from within AutoVISION in the same way a regular calibration file would be loaded.

In the example below, the results are in pixels because the calibration file is not loaded.

Now, navigate to the File menu and select Calibration > Load Calibration File. Select the calibration file you just saved.

Measurements will now be reported in the units from the calibration utility.

In the image above, the two distances are reported as 55998.5 microns and 55989.7 microns, where the nominal values should be 56000 microns. This means that the errors are 12 microns or less. With one pixel representing 89 microns, this is well under a quarter of a pixel. This target shown above was a printed paper target with less-than-optimal lighting. Better results can be expected when greater care is taken with the calibration process.

The calibration is downloaded to the camera at the same time as the job file.
