Abstract
Provided is a metering device and a metering method. The metering device includes a Hall sensor configured to output a Hall voltage generated by a magnetic field generated from a power supply line, an analog-digital converter configured to receive a voltage signal between a minimum voltage value and a maximum voltage value to convert the voltage signal into a digital signal and output the digital signal, an output adjustment unit connected between the Hall sensor and the analog-digital converter, and configured to attenuate and output the Hall voltage when the Hall voltage output from the Hall sensor is larger than the maximum voltage value and output adjustment information that adjusted the Hall voltage, and a control unit connected to the analog-digital converter and the output adjustment unit, and calculate the digital signal output from the analog-digital converter and the adjustment information output from the output adjustment unit to calculate wattage.
