摘要
Digitally controlled eddy current test apparatus for detecting flaws, their extent and location. The apparatus provides absolute and differential measurements. The apparatus employs multi-frequencies with the signals from the test coils mixed in a predetermined manner to reduce unwanted signals such as may be introduced by wobble (lift-off) and support plates.
