Measuring resistance

  • The next three steps will show you how to measure resistance with your multimeter.

  • To begin, make sure no current is running through the circuit or component you want to measure. Switch it off, unplug it from the wall, and remove any batteries.

  • Remember that you'll be measuring the resistance of the entire circuit. If you want to measure an individual component such as a resistor, measure it by itself—not with it soldered in place!

  • Plug the black probe into the COM port on your multimeter.

  • Plug the red probe into the port labeled with an Ω symbol (in this case, the right port).

测量电阻

接下来的三个步骤将向您展示如何使用万用表测量电阻。

开始时，确保没有电流通过要测量的电路或元件。关闭电源，拔下墙上的插头，取出电池。

请记住，您要测量的是整个电路的电阻。如果要测量单个元件（如电阻器），则应单独测量，而不是在焊接到位的情况下测量！

将黑色表笔插入您的万用表上标有COM字样的插孔

将红色探针插入标有Ω符号的端口（此处为右端口）。
