Abstract
An electric device has an electric power measurement unit with an electric power detection element measuring consumed electric power and an information communication element transmitting the measured power. An electric power meter has an information communication element measuring and transmitting total electric power consumed indoors. An information processing unit stores the measured values in every predetermined sampling period. If a difference α of two measurement values of the electric power detection element is a finite value, the information processing unit calculates and stores both a difference β of two measurement values of the electric power meter corresponding to the two measurement values and β/α, and calibrates the amount of electric power consumed by the electric device and that is measured by the electric power detection element using a median of values of β/α obtained in a predetermined measurement period or a median of a predetermined number of values of β/α.
