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.”
This isn't your expensive, flashy type of multimeter, this is for all those starving students that need to buy their first good, low-cost digital multimeter. This meter doesn't have the ability to auto-power off, it isn't capable of auto-ranging, and it won't be able to measure frequency. However, with this multimeter you WILL be able to measure DC Voltage from 200mV to 600V, AC Voltage from 200V and 600v, DC Current between 200uA to 10A, and Resistance from 0 to 20M Ohm. We even left a meter on to test the battery life - it lasted more than 170 hours (7 days) before the included 9V gave out!
