    • A measuring apparatus is capable of separately measuring at least one of the purely resistive component and the reactance component of a measured circuit. The measuring apparatus applies an AC voltage to the measured circuit and detects a current flowing in the measured circuit. When doing so, a first detection signal whose amplitude changes in accordance with an amplitude of a real component of the current and a second detection signal whose amplitude changes in accordance with an amplitude of an imaginary component are generated. The at least one of a purely resistive component and a reactance component of the measured circuit is then calculated using the first detection signal and the second detection signal.
    • 测量装置能够分别测量测量电路的纯电阻分量和电抗分量中的至少一个。 测量装置向测量电路施加AC电压并检测在测量电路中流动的电流。 当这样做时,产生其幅度根据电流的实分量的振幅而变化的第一检测信号和其幅度根据虚分量的振幅而变化的第二检测信号。 然后使用第一检测信号和第二检测信号计算测量电路的纯电阻分量和电抗分量中的至少一个。
