Abstract
Provided is a Hall current measurement tool device, comprising a barrel type connecting line, a switch power supply, a terminal resistor and a Hall sensor. The hall sensor comprises three pins, wherein a second pin is in connection with one end of the terminal resistor, and the other end of the terminal resistor is in connection with the ground of the switch power supply; a first pin of the Hall sensor is in connection with the anode of the switch power supply; a third pin of the Hall sensor is in connection with the cathode of the switch power supply; the barrel type connecting line is in connection with two ends of the terminal resistor. The advantages are that Hall current measurement not only can measure alternating quantity, but also can measure direct current quantity; direct current component can be measured in current quality analysis and analysis results are more accurate.
