TA-0425: LCR Fixture or Kelvin Clip - Tweezers or BNC, Bananas and Crocs

Wow! You have a good selection Tony. My only 4 wire is the Fnirsi battery internal resistance meter that has crude and stroppy cables.

Witam fajne przewody ... pozdrawiam

Great video as usual Tony! Very interesting to see the different levels of sophistication in the test signals of the various models of LCR meters. That was very helpful. I have a Hantek meter like the one you showed and purchased a Kelvin clip kit from VoltLog where I built my own 4-wire clips. In those, both wires came in one side of the handle, but the sense wire simply crossed over the hinge of the clip and up to the opposite jaw. Cable length was essentially the same with no continuity between the jaws when open. Love your work, thanks for the content! - JRH

Hey Tony! Ik heb zelf ook zo'n Kelvin kabelset met beide kabels aan één zijde van de connector, maar ieder van de kabels gaat gewoon naar zijn eigen zijde van de krokodil. Maar dat weet jij natuurlijk ook 😉 mooie collectie anyway 👍🏻

Even though they will fit, these might not work with some LCR meters, such as the HP digital bench type. They specify several ways of attaching the shields together, and to ground, for certain measurements.

Keysight has an Impedance Measuring Handbook available on their site which discusses different cable configurations and their advantages and disadvantages. Quite helpful especially at higher frequencies.

Just ordered a pair.

Nice educational video as usual... Thanks Tony... TOP #1...✌

This is so wonderful! My odds and ends explained.

Hi Tony. Valuable video presentation. Alternatively, one can become handy with (nano)VNA and do a much wider frequency sweep. You still need different component fixtures, like maybe separate for through hole and smd. Oftentimes is this approach maybe some more work as you need to calibrate, but if you have a few standard setups, you can save the cal reference for a specific setup and doesn't need to calibrate every time, I suppose.

Great video.

Always enjoy your videos, Tony! 👍

Hi Tony, another great informative video, thank you. Also, thank you for subscribing.👍

You could have just checked continuity between the individual jaws of ech clip with the banana plugs to confirm that both jaws were actually wired separately.

Great informative video, thank you, Tony!
P.S. I bought a Kelvin test lead from JZDZ for my Keithley 6500 on AliExpress a month ago for 17 euros, and they turned out to be very high quality. I'm surprised...

Very nice video, Tony. I am still surprised how you and I have many of the same pieces of test equipment. I also have most of the test cables and fixtures you showed in this video. Again very informative and well produced video.
