Abstract
A switchless, hand-held probe and method for detecting and alerting a user to the presence of an AC voltage on a conductor that minimizes the intermittent activation of the probe's indicator due to static charge build-up. The probe comprises an antenna, an indicator, detector circuitry and activation circuitry. The probe alerts a user through the use of an indicator to the presence of electrical energy on a conductor. The antenna senses the electrical energy radiated from the conductor. When the electrical energy sensed by the antenna satisfies a particular measurement threshold, a signal is generated by the detector circuitry and received by the activation circuitry. The activation circuitry activates the indicator after a sufficient number of signals are received from the detector circuitry during a given period of time.
