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.

Hand-held voltage detection probe

The present invention is directed to a non-contact detector for sensing a periodically varying magnetic field. The non-contact detector includes a probe having at least one magnetic sensor used to sense a magnetic environment generated by current running through a conductor. The detector includes means for periodically varying the magnetic environment and sensing means that is associated with each magnetic sensor that produces an electrical signal representative of the change in the magnetic environment. The detector also includes means for delivering a usable representation to a user in response to the sensing of the periodically varying magnetic environment.
