MEASUREMENT DEVICE AND MEASURING METHOD FOR AC SIGNAL AND RECORDING MEDIUM THEROF

摘要

PURPOSE: A device and a method for measuring an alternating current signal and a recording medium thereof are provided to obtain direct current value by accurately measuring the waveform of an alternating current signal. CONSTITUTION: An alternating current generating source(100) generates an alternating current signal to measured. A reference direct current generating source(200) is electrically connected to the alternating current generating source and generates a reference direct current signal. A direct current converter(300) generates a synchronizing signal and a trigger signal. A digital-analog converter varies the reference location of the reference direct current signal. A control unit(400) produces effective value of an obtained alternating current signal waveform.
