Abstract
A procedure of applying the d-c potential drop technique using the clo sely coupled probes to NDE of a 3-D surface crack is newly developed T he calibration equation for three sensors which differ in the distance between the probes is derived. Experiments validated the use of the c alibration equation for the NDE of cracks. The method to use the three sensors properly based on the measuring sensitivity is shown.
