APPARATUS AND METHOD FOR MEASURING CURRENT OF BATTERY OPERATED SYSTEMS

摘要

PURPOSE: A current measuring apparatus of a batter power system and a method thereof are provided to offer current consumption and power information intuitively to a user by displaying a histogram of power status and consumed current. CONSTITUTION: A first resistance(R1) is connected between a tested device and a power source supplying voltage to a device under test. An amplifier amplifies the voltage difference of both ends of the first resistance. An analog to digital converter(120) changes the output voltage of the amplifier into a digital signal. A digital signal processor(130) uses the output signal of the analog to digital converter.
