In this video I go through the basic functions of a cheap multimeter, I cover how to measure AC and DC Voltage, how to measure resistance, how to test for continuity and how to measure amps. You can buy a multimeter for $5 at Harbor Freight and it will have these features and be more than enough for a diy’er. They look intimidating at first but once you know how to use the basic features it’s very handy tool to have around the house. Whether you are trying to see if you have current at a wall socket or diagnosing sensors on your car or more delicate diagnosis on a circuit board a multimeter essential.
