Abstract

피측정소자의 입력전압 및 출력전압을 소정배율로 강하하고, 그 강하된 두 전압차를 산출한 후, A/D 변환하여 제어부에 입력한다. 제어부는 그 전압차를 앞서의 역산으로 산출하여 피측정소자의 양단전압을 계측한다.The input voltage and the output voltage of the device under measurement are dropped at a predetermined magnification, the two voltage differences are calculated, and then A / D converted and input to the controller. The control unit calculates the voltage difference by the inverse of the above, and measures the voltage at both ends of the device under measurement.
