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 includes an antenna, an indicator, and activation and detection 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 plurality of times during a period of time, the activation and detection circuitry activates the indicator.

A probe for alerting a user to the presence of electrical energy on a conductive member, the probe comprising:
- an antenna to sense electrical energy;
- an indicator to alert a user when activated by activation and detection circuitry;
- activation and detection circuitry connected to the antenna and the indicator, the activation and detection circuitry for reducing intermittent activation of the indicator due to static charge accumulation by activating the indicator when the electrical energy sensed by the antenna has met a measurement threshold a plurality of times during a period of time.
