Are you confused by all the symbols on a multimeter? Are you wondering what that little line with a squiggle next to it could possibly mean? Perhaps you're still learning how to use your multimeter or maybe you've had yours for a while, but are just unsure on what a couple of the symbols actually mean because you've never had to use that setting. This guide is for you. We're going to explain in detail what settings and symbols mean on the common meter.
The last thing you want when troubleshooting an important issue with your digital multimeter is to misunderstand what the reading means. This could be especially dangerous if you were trying to undertake a continuity test and accidentally had your instrument set to the Volt measurement.
We hope that you have found this guide useful. Having even a basic electrical knowledge and your own testers will help you greatly, and could save you thousands of dollars in electrician costs. In saying that, voltage and current can be extremely dangerous - even at small measurements, be sure to call an electrician if you have any doubts and never carry out any work that requires you to be licensed.
what does lightning symbol on the screen next to the number mean?
That means “Unsafe voltage. The measured input voltage is above 30V, OR voltage overload condition”. Hope this helps.
