Abstract

To increase power to a measurement device, the measurement device measures a first voltage across the measurement device. The measurement device then determines an operating current based on the first voltage. The operating current is a maximum current that the measurement device draws without dropping a measurement device voltage below a threshold voltage to prevent resetting of the measurement device. The measurement device then generates a signal to change the power to use the operating current.
