Étape 5
To complete your continuity test, place one probe at each end of the circuit or component you want to test. As before, if your circuit is continuous, the screen displays a value of zero (or near zero), and the multimeter beeps.
  • To complete your continuity test, place one probe at each end of the circuit or component you want to test.

  • As before, if your circuit is continuous, the screen displays a value of zero (or near zero), and the multimeter beeps.

  • If the screen displays 1 or OL (open loop), there's no continuity—that is, there's no path for electric current to flow from one probe to the other.

  • Continuity is non-directional, meaning it doesn't matter which probe goes where. But there are exceptions—for instance, if there's a diode in your circuit. A diode is like a one-way valve for electricity, meaning it will show continuity in one direction, but not in the other.

要完成一次连通性测试,只要将两支表笔碰触需要测试的电路或者元器件两端即可

如之前提到的一般,如果您要测试的电路是连通的,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。

如果屏幕显示1或者OL(开路),那就表示这个电路不连通——这意味着电流无法从一端流至另一端

电路通断是无方向性的,这意味着哪个表笔在哪端都不重要。 但是也有例外,例如,如果电路中有一个二极管。 一个二极管就像一个单向阀一样,意味着它将在一端会显示通,而在另一个方向则是“没有”。
