4-wire

This video explains the importance of using Kelvin contacts or remote sense when measuring high currents. The speaker demonstrates how voltage drops in the measurement wires can affect accuracy, especially at high currents. They show how using separate sense wires to measure voltage directly at the device under test eliminates this error.

This video demonstrates how to make low-cost four-wire Kelvin probes using recycled household items. The creator uses sewing machine needles, interdental brushes, and old scart cables to create probes that are ideal for measuring milli-ohms and finding shorts. The process is quick and easy, taking only a few minutes per probe.
