Abstract
A circuit test device includes a housing. The circuit test device includes a circuit disposed in the housing and including an electromagnetic field (EMF) sensor and a signal detector coupled to the EMF sensor. The circuit test devices includes a conductor disposed on the housing and an interface extending through the housing and coupling the conductor to a circuit under test (CUT). The EMF sensor is configured to generate a signal in the presence of a time varying flow of current from the CUT in the conductor, and provide the signal to the signal detector.
