Beginner Electronics Multimeter Basics
Measure voltage, resistance, and continuity safely
This guide explains how to use a multimeter: choosing the right mode and range, measuring voltage and resistance, using continuity, and avoiding common mistakes that blow fuses or damage circuits.

Know the ports
Use the correct jack for volts/ohms vs current; current often requires a different fused port.
Measure voltage safely
Set to V, start on a higher range if manual, and probe across points without shorting.
Use resistance/continuity correctly
Measure resistance only on unpowered circuits; continuity is for quick open/short checks.
Avoid common errors
Never measure current with leads in the wrong port; replace blown fuses and recheck setup.
