Were you able to test the accuracy and see if it actually scores better?

[@BadDogElectronics]

I did not. I would assume the original leads would be very accurate. I did the mod just to make life easier with the tests I do. The stock cables are just way too short for my situation.

[@sharymens8187]

@@BadDogElectronics Ah oki thank you!

[@guateque1718]

Uni-t and ziboo or zeeboo sell a 4 wire Kelvin lead that fits the de 5000. The leads are pretty good quality too. Saved me from taking my oem attachment apart to do what you did in this video.

[@BadDogElectronics]

Good to know! Thanks for sharing.

Why there is a GUARD terminal exposed? What else can you plug into this black little box?

[@BadDogElectronics]

The Guard terminal is used to prevent capacitive coupling. It is in essence acts as shield for the two (4) terminals. You can plug in any capacitor, inductor, or resistor (within it's spec range) to be measured with a "high" degree of accuracy.

Do not use the coax cable.

[@BadDogElectronics]

Thanks for adding that. Yeah, I'm sure some have tried to use coax. As you stated, not ideal.

[@michalsio2852]

@@BadDogElectronics why not to use a coax cable?

[@BadDogElectronics]

@@michalsio2852 Coax cables would technically "work", but the accuracy would not be even remotely close, there's a huge difference in the composition / resistance etc, of the conductors. Copper center conductor and some type of composite shield. In order to have a high degree of accuracy the two (four) conductors must be matched closely.

[@michalsio2852]

@@BadDogElectronics is that really important to have closely matched conductors although LCR meters make their own calibration?

[@BadDogElectronics]

@@michalsio2852 I think it's very important to have the same resistance on the conductors. Also, different wires attenuate frequencies differently. If the goal is precise measurements, than one should take every precaution to put the 'best' info in, to get the 'best' info out. Hope this helps!
