Abstract
PURPOSE: To enable combined inspection, by setting one of the current feed terminals of a variometer at the ground potential and bringing the ground potential part of an eddy current flaw detector into contact with a wire.
CONSTITUTION: The measuring section of a variometer 2 comprises a pair of current feed terminals 7, 7' and a pair of voltage measuring terminals 8, 8'. One current feed terminal 7 at the side of a flaw detector 3 is connected as a grounded terminal to the earth U. The measuring section of the eddy current flaw detector 3 comprises a high-frequency coil 11 and a measuring coil 12. A roller-type grounded terminal 13, which comes into contact with 1, is provided on a part of the measuring section of the flaw detector 3, which is located at the side of the variometer 2. The grounded terminal 13 is connected to the earth U and a current feed circuit 4. The variometer and the eddy current flaw detector are thus provided with grounded potential parts respectively so that a change factor from each of the variometer and the flaw detector toward the other is conducted out. As a result, the homogeneity and surface state of the wire can be jointly inspected.
