ABSTRACT:
An eddy current analyzer is employed to locate and map a substrate edge hidden from view by a cover plate. A probe has an axial bore in which rests a spring-biased marker. The analyzer scope traces locate hidden points along the edge and the marker maps these along the cover plate. A line drawn between the points locates the edge thereby enabling holes to be drilled at equal distances from the hidden edge.
