My father-in-law gifted me this Sears Craftsman 8-function Multimeter for Christmas and I've just gotten around to unboxing it and finding it's permanent home in my shop. I wasn't quite sure what to do with a multimeter (or multi-meter as it is sometimes spelled), but Nat's Dad also sent along with CNET piece that explains all that this tool can do . Here's the list: 1. Test batteries 2. Check extension cords 3. Determine the life of lightbulbs 4. Identify the 'hot' wire 5. Find bad switches So...turns out, it wasn't all bird stuff at Christmas this year, right?!?
