A multifunction testing and measuring device having a probe body with an elongated portion extending outward from a rearward main body portion to a hook-shaped forward end, the hook-shaped end useful for isolating a conductor under test, a slide closure member adapted to slide longitudinally forward from a rearward open position to a forward closed position, the closed position useful to capture the conductor under test within a space encircled by the combination of the hook-shaped end, the closed slide closure member, and the rearward main body, with the space encircled including a current sensing zone, and having test leads integral to and stowable on the main body. The multi tester comprises circuitry adapted for detecting a magnetic flux generated by an electric current passing through the conductor under test positioned within the current sensing zone, for sensing current and inrush current, as well as selectably measuring voltage, continuity, and resistance between the test leads.

A current measuring device having a probe body with an elongated portion extending outward from a rearward main body portion to a hook-shaped forward end, the hook-shaped end useful for isolating a conductor under test, a slide closure member adapted to slide longitudinally forward from a rearward open position to a forward closed position, the closed position useful to capture the conductor under test within a space encircled by the combination of the hook-shaped end, the closed slide closure member, and the rearward main body, with the space encircled including a current sensing zone, and circuitry adapted for detecting a magnetic flux generated by an electric current passing through the conductor under test positioned within the current sensing zone. A release button for moving the slide closure member serves as a switch to turn on the meter/tester/device when the jaw/slide closure member is opened.

Hook meter

The present invention provides a current measuring device including a probe body having an elongated portion extending outward to a hook-shaped end wherein the hook-shaped end useful for isolating a conductor under test, a U-shaped magnetic core positioned upside down within the probe body and forming the hook-shaped end of the probe body wherein the U-shaped magnetic core has an interior surface extending between a first end and a second end and defines a current sensing zone therebetween, a first Hall sensor disposed upon the first end of the interior surface of the U-shaped magnetic core, and a second Hall sensor disposed upon the second end of the interior surface of the U-shaped magnetic core wherein the Hall sensors are capable of detecting a magnetic flux generated by an electric current passing through the conductor under test positioned within the current sensing zone. The device may further include amplifier circuitry electrically interconnected with the Hall sensors for amplifying electrical signals therefrom, an output board interconnected with the amplifier circuitry for receiving an amplified output signal from the amplifier circuitry and for providing power to the amplifier circuitry, and a digital multimeter extending rearward from the probe body opposite the hook-shaped end and electrically coupled to the output board.
