The multimeter tests continuity by sending a little current through one probe, and checking whether the other probe receives it. If the probes are connected—either by a continuous circuit, or by touching each other directly—the test current flows through. The screen displays a value of zero (or near zero), and the multimeter beeps. Continuity!
  • The multimeter tests continuity by sending a little current through one probe, and checking whether the other probe receives it.

  • If the probes are connected—either by a continuous circuit, or by touching each other directly—the test current flows through. The screen displays a value of zero (or near zero), and the multimeter beeps. Continuity!

  • If the test current isn't detected, it means there's no continuity. The screen will display 1 or OL (open loop).

万用表通过其中一支表笔输出一个微小的电流,然后确认另外一支表笔是否接收到这个电流来测试电路的连通性

如果电路连通——无论是电路确实连通,或者是将两支表笔相互碰触——测试用的电路部分是连通的。屏幕会显示一个0的值(或者接近于0),并且万用表会发出“哔”的响声。表示电路连通

如果没有收到测试的电流,这表示电路不连通。屏幕将会显示1或者OL(OL: 开路)
