GoupchnLCR Meter Test Leads Terminal Kelvin Clips Cable Wires to 4mm Safety Banana Plugs 1.2m/3.94ft for DMM

Surprisingly good! For the price, they are a bargain. I’ve been using them for quite awhile now and they are doing great.

Well-built set of Kelvin clips. Gold coated alligator clips are well aligned and grippy yet small enough and unintrusive, banana plugs have overmolded strain reliefs, there are properly designed retention clips for the pair of cables along the way, not just heatshrink, and cables arrive properly on each side of the clip, not combined like in cheaper sets. All that for the same price as the lesser built ones. Now permanently attached to my HP 4262A LCR meter.

These leads are OK if you're looking for normal cables with Kelvin clips to do 4-wire measurement. But the cables are not shielded -- so if you're aiming to use this, for example, with the DER DE-5000 LCR meter, these will not work as they will not pass self-calibration with the DE-5000. These leads are silicone and use 14 AWG wires.

I bought these just to test the 4 wire resistance feature on a Keithley meter I was refurbishing, assuming I would buy/make a better set in the future. However, these exceeded all expectations and will meet my needs long term. Wires are good length and have supple silicone insulation - these are not stiff like some cheap probes. Banana jacks fit snugly. The alligator clip jaws align well. Repeatability of 4 wire measurements is within 4 milli Ohms - 20ppm for 200 Ohm full scale. I used a paint pen to mark the "force" side on the cable and the clip jaws to improve measurement repeatability.

Good build quality, works perfectly, showed no tendency to fall apart. I used my (dumpster dived) Fluke bench meter to measure some suspect automotive fuses. The 5A fuses (ATM-LP in this case) should be 17 milliohms and they were. Fake Chinese fuses come out much lower, like maybe 1-2 milliohms.

Very well made. Plenty of lead length. The leads are very flexible as you would expect in this application. Crocodile clips grabbing strength is very strong. Crocodile clips are a little bigger than I anticipated but ok.Had to cut away the plastic outer sleeve (gray portion) that covers the banana connectors to expose the contacts as the sleeve interfered with the connection to my vintage HP 3478 Multimeter. This did not compromise the connection or function after modification.Worked fine with my older (2-wire) Fluke 79 Multimeter before and after modification.

Feels like a professional 4-wire probe. The cable is good silicone. The probe is "heavy", much better than some chinese I bought.

Works as expected
