Abstract
A measurement apparatus that measures a current consumed by an electronic device is provided. The measurement apparatus includes: a power supply output terminal connected to the electronic device; a power supply voltage output section that output a power supply voltage; a diode switch section having two diodes connected in parallel between the power supply output terminal and the power supply voltage output section so as to rectify in the direction opposed to each other that applies the current consumed by the electronic device between the power supply output terminal and the power supply voltage output section when the electronic device is in operation; a rest time drive section that applies the current consumed by the electronic device to the power supply output terminal so as to keep the voltage of the power supply output terminal the same as the power supply voltage when the electronic device is in resting state; and a rest time current measurement section that measures the output current value of the rest time drive section.
