In this mode, the multimeter sends a little current through one probe, and measures what (if anything) is received by the other probe. 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—in this case, 0.8). Very low resistance is another way of saying that we have continuity.

  • If no current is 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收到了多少电流来确定阻值

如果两支表笔之间是连通的——不论是通过电路连通或是直接触碰两支表笔——都表示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——在这只万用表上的值为0.8)。得到一个非常低的电阻值即表示该电路是连通的。

如果电路不连通,这表示电路是开路。屏幕会显示1或者OL(开路)
