    It's not the leads that cause this, it's the connection to what you are measuring. Often a film of grease on the probe from your skin. Clean them with alcohol and zero your meter, then check for repeatability. If your experiencing this with the alligator clips, clean the threads and make sure they are tight.

    I also find that the telcom leads are a great addition at times. The multi-pin piercing clamp works well on small gauge wires.

      I had that set many years ago in fact 30 years ago about when I bought the Fluke 87 (the original 87) and because they didn't work well they're still like new and I just tried it again, clean with contact cleaner whatever, I never get it to work well. I have no problem with other sets of leads though and I have many.

        That's odd. Can you give me more detail as to what was the problem with them. If you had the original 87A model, it was recalled due to the selector switch. I still have mine, but the screen has lost a half of a digit. It's still my favorite after the Simpson 260. Especially because of the graphing bar that helps determine if you having a connection problem.

          If you want I can send them to you for evaluation. Yeah I had the original 87 and it had bad display twice. First time Fluke fixed it for free the second time they said can't fix it and offered me $100 toward the 189 which I went for.

          By the way can we post pictures here? I would like at least posting some pics and also test the leads again tonite and tell you what's wrong.

    I recently ordered this set from Amazon;

    They are clearly not made for commercial use, but they are surprisingly good for low voltage measurements, or those times where you don't have enough hands to hold the probes down 🙂 At $21 they are cheap enough to toss if/when I break them…

      That doesn't seem like a bad deal especially with the quantity you are getting. Like you said not for commercial, but in my experience the amount of wire low/vol has is quite excessive.

    I'm not a fan of PVC insulation. To stiff for my liking. Silicone is not the answer either, To easy to cut. Hypalon is expensive, but tough and long lasting as well as being supple. Fine annealed silver coated wire is the best for both conductivity and being supple. Gold or silver plated tips work better than Nickle. When you resharpen, they lose their corrosion protection. And conduction contact reliability. That's why the high cost of good ones.

    Interested to hear how these probes work for you. We have all had the probe that gets shorted/overloaded, or get's a intermittent open in the field. The whole reason for always carrying a extra pair. I've never had the SMT tweezers. I can see where they would be a big help looking for a bad diode or resistor.

    You can usually find Fluke test leads at either a good electronics shop or there is always Grainger as well as Johnstone's if you have one near your location.

      You still have electronics shops? We've lost almost all of them in my area. SMT and the microchip technology has starved them out.
