也可以作为绝缘电阻表使用。
选项1，完整的微电阻表。
用万用表来作电阻表使用时，你需要选择电阻量程。
To get the multimeter to function as an ohmmeter , you will need to select a resistance range.
其功能相当于电压源、电流源、电压表、电流表和电阻表的综合体。
Its function is equivalent to the voltage source, current source, voltage meter, current meter and resistance meter.
电阻表的工作原理为，生产一个电流流过测量的元器件，在其上生产电压，并测量其值。
Ohmmeters work by passing a small current through the component and measuring the voltage produced.
绝缘电阻表以前是按标度尺弧长定义的弧长误差，现行国家标准规定以指示值的百分数表示。
Formerly the arc length error for the insulation resistance instrument is defined by scale arc length. At present national standard determines that the percentage of indicated value expresses it.
