Introduction

Every fixer should know their way around a multimeter, which has just north of a zillion uses for testing electronic components and circuits. Follow along to master the three most basic functions of a multimeter.

Part 1: Testing Continuity

Part 2: Measuring Voltage

Part 3: Measuring Resistance

To learn how to use your multimeter to make advanced measurements such as current and capacitance, check out this guide.

What you need

1. Step 1 Testing Continuity

   

   • A continuity test tells us whether two things are electrically connected: if something is continuous, an electric current can flow freely from one end to the other.

   • If there's no continuity, it means there is a break somewhere in the circuit. This could indicate anything from a blown fuse or bad solder joint to an incorrectly wired circuit.

   • Continuity is one of the most useful tests for electronics repair.
