摘　　要：根据数字万用电表电容档运用电容—电压 (C -U )转换器测量电容的原理 ,利用在交流信号测量电路中电感电抗与电容电抗可等量代换的特点 ,提出了用普通数字万用表电容档快速测量电感的方法 .According to the principles of the digital universal meter using the electric capacity shelf of the switching device of the electric capacity voltage( C U )to measure the electric capacity,the article proposes that the digital universal metre electric capacity shelf be used to measure inductance quickly by making use of the fact that the reactance of inductance is equivalent to that of electric capacity in AC measurement.
