| Abstract: | All instantaneous value of electric current and voltage of the tested electric circiut was been acquired by interconnect communication between a micrcomputer and digital storage oscilloscope. All tested value was been analysised , processed by The Fourier Transform ,so, the power factor of tested circuit was been acquired.A testing function of power factor in PM3350 Digital Storage Oscilloscope was developed. |
