Abstract
Calibration of an eddy current inspection system having an eddy current probe and a rotatable turntable is accomplished using a circular calibration standard having a notch of known dimensions formed therein. The calibration standard is mounted on the turntable for rotation therewith. The eddy current probe is positioned adjacent to the calibration standard, and the calibration standard is then rotated so that the probe scans the notch. By providing a rotating scan of the calibration standard, higher scan speeds and more accurate calibrations are achieved.
