Fluke TL175 high resistance?
« on: December 10, 2020, 11:44:13 am »
I have a pair of new(ish) Fluke TL175 multimeter leads. Their resistance is ~ 0.4 ohm each. Other leads I have are ~ 0.01 to 0.02 ohm (measured on older Fluke benchtop DMM). Can anyone confirm if the 0.4 ohm for TL175 is typical of these? Cheers.

You can try running 10 amps of current through them and see the heat.
"Bad" wires at this current can melt.

As far as my experience is concerned, some Fluke test leads are not very good. To give you a quick overview, I took a wooden clip to simulate the same pressure, always using the depression with the Flukes in contrast to Brymen and ProbeMaster which are even.

With respect to the TL175 model, there are two versions: yellow vs. black



The yellow leads were part of my "Fluke 289 FVF" kit and are quite good, apart from the plastic feeling: 0.0675 Ohm



The black leads were part of my "Fluke 87V" and have a very poor quality: 0.6440 Ohm



The best quality do have the ProbeMasters: 0.0411 Ohm



But, considering the price of less than 10 Euro,...



...the Brymen do have the best value and feeling: 0.0469 Ohm





Cheers.
Due to the massive "EEVblog forum attachement bug", I am now using an external picture hoster, till it is solved...
