Multimeter Continuity Symbol (Guide)

If you are not familiar with the term continuity, this article might help you a great deal. Today we are planning to discuss the multimeter continuity symbol. The continuity symbol is one of the most prominent multimeter symbols.

The continuity symbol might be different according to the model and brand. But, in most models, if you can locate a diode symbol that is similar to a triangle with a single line near the right side, that is the multimeter continuity symbol. There should be a soundwave symbol close to the diode symbol. (1)

What is it used for?

Simply, a continuity test is used to test the resistance of two points. When two points have very low resistance (few ohms), those points are electrically connected. We called this a closed circuit, and when a digital multimeter detects a closed circuit, it releases a tone.

If there is a considerable amount of resistance between two points, we call that, an open circuit, and the digital multimeter does not release any tone. In other words, measuring continuity helps us determine the availability of electricity between selected points.

Using the Mode

Here we will discuss how the continuity test works. For that, first, you need to locate the continuity symbol on the multimeter. There are several multimeter symbols that you have to deal with while using a multimeter. Here we will measure continuity.

If you can find a diode or wave symbol in your digital multimeter, that is the continuity symbol. So, let’s get started on our short demonstration of a continuity test.

Step 1: Set the multimeter dial to the continuity setting. Now, you can measure continuity.

Step 2: Touch the black and red probes to make sure the multimeter is working.

Step 3: Switch off and unplug the device or the circuit that you want to test.

Step 4: Touch one end of the circuit with the black probe. Then touch the other end with the red probe.

Step 5: Wait until the multimeter gives a proper reading. (2)

Step 6: If the reading is zero, that means perfect continuity. The multimeter will beep continuously. However, the continuity does not need to be zero every time to be safe.

Step 7: If the reading is 1 to 10, check the device manual to clarify the resistance levels. If it is above 10, that means that circuit has poor continuity.

You now should know how to find a continuity symbol in a multimeter. So, make sure to apply the things that were discussed above for your next DIY project.
