Abstract:
A method of calculating a current correction formula may include first measuring voltage values at each of current measuring parts configured to measure currents in socket parts of a power strip in a state in which no current flows in the socket parts, second measuring the voltage values at each of the current measuring parts in a state in which a current flows in one of the socket parts, and calculating a correction formula formed by a inverse matrix of a matrix having as its elements differences between the voltage values measured by the second measuring and the voltage values measured by the first measuring.
