Digital Multimeter
Basic
The digital multimeter (DMM) is an essential tool in every electronic enthusiasts arsenal. The SparkFun Digital Multimeter, however, is not your average multimeter, it features a loud continuity sound, current/voltage sense, and quality probes. You can use the multimeter to measure DC and AC voltage, DC current, resistance, continuity, and test diodes. With this version we've done away with the bright flashy colors that can get us into trouble and gone with a nice, neutral gray. This multimeter should provoke no strong feelings one way or the other, we know this because our guts say "maybe."
