Abstract
The systems and methods of the present disclosure use measurement circuitry that includes first and second circuits, a selecting circuit, a determination circuit, and a setting circuit. Each of the first and second circuits measures voltage or current sensed by a sensor. The selecting circuit selects the first circuit to provide the measured voltage or current values. The determination circuit determines whether the measured voltage or current values reach a predetermined level. The setting circuit changes a setting of the second circuit from a first setting to a second setting if the measured voltage or current values reach the predetermined level. The selecting circuit selects the second circuit to provide the measured voltage or current values when a first predetermined time elapses after changing the setting of the second circuit. The selecting circuit also changes a setting of the first circuit from the first setting to the second setting after selecting the second circuit.
