Abstract
An apparatus (30) locates and measures any seam or other discontinuity (18) within a metal enclosure (10) by determining the characteristic inductance of the discontinuity. A pair of probes or electrodes (40, 42) are connected via a balun (46) to a network analyzer (56). When the probes are placed on either side of the discontinuity, the network analyzer can measure the length of the discontinuity by equating the discontinuity to an inductor.
