Abstract
A digital voltage indicator includes a probe having a first electrode including a hollow portion and a probe tip projecting from the hollow portion, a second electrode extending into the hollow portion and spaced therefrom, and dielectric material disposed between the second electrode and the hollow portion. The indicator may include a reference conductor connected to the second electrode and detection circuitry connected between the probe and the reference conductor for detecting a voltage difference therebetween, and an annunciator connected to the detection circuitry for displaying the measured voltage.
