Version 2



    Bench DMMs have an extra set of banana jacks called "sense." Known as a Kelvin or 4-wire measurement, these inputs accurately measure small resistances. Like, milliohms small. In this video, learn how to use a multimeter with 4-wire capability, prove 4-wire is more are accurate (in some cases), and a trick to get more accurate measurements with traditional 2-wire techniques.
