Fluke TL175 meter leads

[Dsg319]

Having an issue with my fluke twistguard Tl175meter leads. Have loved them up into this point, super flexible and bendable with no memory of the bends.

Plan on doing some bench test this weekend during the rain, and noticed tonight that when I went to “ohm out” my leads together. I was getting higher than average values. Around 2-2.5ohms.

So I replaced with original leads that came with my fluke 117 and almost zero’d my ohm readings back to 0.5ohms +/- a little bit.

Some test to assure it was the leads and not the meter consisted of.

1.Removing the com lead and placing tip of red lead into it just to test that single lead itself. And there lied almost all the resistance I was reading in the red lead.

Black lead still was 0.9ohms.

2. Replaced with original leads from fluke 117, read resistance across the fluke TL175 and read the same values as when they were plugged into the meter. Around 2.5ohms.

3.Also plugged the TL175 into another meter and read around the same high values for just the leads themselves.

What could cause this? There not that old, clean and always well taken care of.

What can I say that you don't already know. The lead is defective, they go bad. I can say the same thing for one of my Tektronics X10 probes. Not old or abused but when I went to use it it didn't work.

I've got several old, failed, fluke meter leads. Usually the break is in the socket end that plugs into the meter and for some reason, I have yet to determine, the black leads fail more often than the red ones. I cut the ends off and solder on insulated alligator clips or stake on connectors to make different kinds of jumper wires, they're better than an extra set of hands and a prehensile tail when I'm troubleshooting

My co-worker has the same exact set and the same problem as well. Comfortable leads... it’s a shame.
