  • To complete your continuity test, place one probe at each end of the circuit or component you want to test.

  • It doesn't matter which probe goes where; continuity is non-directional.

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

  • 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.

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

不必多想哪支表笔放在哪个位置,电路连通性测试不分极性

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)

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
