ABSTRACT:
Apparatus, and associated methodology, for testing shielded, multipair cables to verify conductor and splice continuity comprises: means (120,122) for magnetically coupling excitation source (110) to the conductor (106) under test; and means (121,123) for magnetically coupling a series path comprising the conductor under test to detector means (130,131,140-143,150,160,200-207,301-313). The detector means includes means (160) for indicating that the conductor (106) and splice (108) are electrically continuous whenever the detector means senses a signal above a predetermined threshold.
