More Information
Summary:A wearable electric field detector has a housing mountable on a user's person and including a sensing circuit responsive to an electric field to generate a signal which varies in proportion to the strength of the sensed field, and an alarm circuit coupled to the sensing circuit for producing an intermittent audible alarm signal, which has a repetition rate varying in proportion to the strength of the field, and a visible alarm signal. A mute circuit is manually activatable for selectively muting the audible alarm and then automatically reenabling it after a predetermined time period. The detector includes a manually-actuatable test circuit. There is no on-off switch, the detector being disabled by being disposed in a shielded carrying case.
