Abstract
The insulation of a plurality of grounded wires may be tested subsequent to fabrication and prior to spooling by use of a corresponding plurality of modular circuit boards installed in a continuity tester. Each modular circuit board has its own on board DC power supply and clock generator for enhancing isolation, thereby decreasing crosstalk between channels and reducing spurious 'sympathetic' faults. AC or DC high voltage testing may be selected. Isolation is also enhanced by using a sheaves separated by teflon insulators, all mounted on a common rod.
