1. A measurement circuit that measures voltage or current of electrical energy generated by a generator, the measurement circuit comprising:

  • a first circuit configured to measure the voltage or current;

    a second circuit configured to measure the voltage or current;

    a selecting circuit configured to select the first circuit to provide the measured voltage or current;

    a determination circuit configured to determine whether the measured voltage or current reaches a predetermined value; and

    a setting circuit configured to change a setting of the second circuit from a first setting to a second setting when the determination circuit determines that the measured voltage or current reaches a predetermined value,wherein the selecting circuit is further configured to select the second circuit to provide the measured voltage or current when a first predetermined time elapses after the setting circuit changes the setting of the second circuit,wherein the setting circuit is further configured to change a setting of the first circuit from the first setting to the second setting after the selecting circuit selects the second circuit, andwherein the first setting is for measuring a first range of voltage or current and the second setting is for measuring a second range of voltage or current.
