Seriously? :palm: --- End quote --- By "Luis Vuitton" he meant Fluke. :) --- End quote --- While Fluke quality may be slipping slightly on some products, I'd hardly put them in the same category as "fashion statement". Yet. Ok, LCR warmed up, so here for shits and giggles is my no-control lead comparison. All leads including the LCR Kelvin clips were cleaned with 99.9% IPA first. Brymen BL21: 0.08410Ω Pomona 6342: 0.09373Ω Keysight 34138: 0.02043Ω Unknown PVC: 0.02052Ω Pomona 6366: 0.08939Ω RS Pro modular: 0.05711Ω Very old and solder burned Fluke TL71: 0.03050Ω Home made banana to banana: 0.00837Ω I do have plenty of other leads I could have included, but I'm late for beer o'clock as it is. |

Just to note the reason you pay for pricey DMM leads is not longevity and quality but the fact the CAT rating and UL markings are actually less likely to be a fat lie wrapped in a shit sandwich. Safety first. Always. |

It seems "unknown PVC" beats all big brand names except one. :) Edit: And only loses to that one by a 0.4% margin(!) |

If I ever feel the need to poke at a distribution panel I'll pull out my Fluke 27 FM. |
