欧姆计 Ohmmeter
（重定向自Resistance measurement）
欧姆计 (ohmmeter) ，又称为电阻表，是一种专门测量电阻的仪器。电机组件阻碍电流流动的性质，称为电阻，单位为欧姆。毫欧姆计专门测量微小的电阻；而百万欧姆计，又称为兆欧计，或高阻表，则专门测量非常巨大的电阻。

（重定向自Resistance measurement）
An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current. Micro-ohmmeters (microhmmeter or microohmmeter) make low resistance measurements. Megohmmeters (also a trademarked device Megger) measure large values of resistance. The unit of measurement for resistance is ohms (Ω).
