4-Terminal Kelvin Connections: What, how and why to use them

Explaining Kelvin Connections (4-Terminal Connections, Sense-Wire Measurements) with practical applications.

[@sangeeth_619]

I was actually looking for a perfect video that explains how the 4 wire measurement system works. Then comes this! Subscribed and a ton of thanks for the well covered explanations.

When I want to use a 4-wire measurement, it’s usually for a much lower impedance DUT than a typical DMM. So I have a homemade 100mA CC box and use it in conjunction with a DMM on mV setting, and multiply the resultant reading by 10 for the milliohm measurement. Just requires a set of kelvin clips.

I couldn't find the video for the "milliohms adapter" that appears at 6:02 here on your channel.

I think I didn´t say that I have already made a video about this adapter or did I? Perhaps we will make at some time make a Kickstarter campaign out of this :-) If you are interested I can send you the handdrawn circuit diagram.

Cliff Matthews try Scullcom Hobby Electronics he has made one with three or four part video

Thank you.

Hi, Thanks for interesting video, but is there already an circuited integrated complete for stumentations ? excuse my english language

[@KainkaLabs]

Is that a question or a statement?

What is a 'Kelvin Bridge'?
