Abstract

A measuring apparatus has a physical amount transformer that transforms a physical amount into a current, a measuring circuit that measures an output current of the physical amount transformer, a power supply circuit that inputs an output of the measuring circuit, a circuit switching unit that switches between a first state and a second state, the first state constituting a circuit inputting the output of the measuring circuit into the power supply circuit, the second state constituting a circuit directly inputting the output of the measuring circuit into the physical amount transformer, and a switching controller driven by the power supply circuit to control the circuit switching unit.
