Abstract
A dual purpose probe for the simultaneous sampling of the voltage and curt at a test point. The device includes a capacitive probe for measuring voltage, and a small solenoid type inductor for measuring current when affixed so that it is at right angles to the wire being sampled. A small, double-sided circuit board has the inductor mounted thereon as well as a small metallic pick up plate which serves as one plate of a capacitor when the probe is affixed in the measuring position, while the conductor being sampled forms the other plate of the capacitor, and the insulation around the conductor serves as the capacitor dielectric.
