The Basics Of Digital Multimeters: How To Use A Multimeter

Not sure what a multimeter is or what you can do with one? Then you're in the right place!



This guide will show you how to use a digital multimeter (DMM), an indispensable tool that you can use to diagnose circuits, learn about other people's electronic designs, and even test a battery. Hence the 'multi'-'meter' (multiple measurements) names.

The most basic things we measure are voltage and current. A multimeter is also great for some basic sanity checks and troubleshooting. Is your circuit not working? Does the switch work? Put a meter on it! The multimeter is your first defense when troubleshooting a system. In this guide, we will cover measuring voltage, current, resistance, and continuity.
