Kelvin leads for DMM

<< < (3/14) > >>

alm:
I have a set of true four-wire probes: Keithley 5805. I bought them used years ago, and definitely didn't pay anywhere near $300. They are nice for measuring PCB traces with negligible error from contact resistance, but the distance between the two probe tips makes it quite hard to use: finding spots you can use it on a PCB with solder mask is often difficult.

Had I just started with these I could have saved the price of the others.  :)

Those B&K TLDK1 Kelvin probe clips look like the Tonghui supplied ones on the TH26011CS fixture, and much higher quality clips than the cheaper Kelvin types found on eBay. Couldn't find them sold individually anywhere tho.

While searching I came across some R&S Kelvin clips and cables with BNC ends, these looked like the cheap eBay cables with the low quality Kelvin clips. Recall the price was ~$330!!!

Anyway, thanks for pointing out the B&K Kelvin cables, with those quality Kelvin clips they are certainly better than anything we conjured up!!

Best,

I purchased some banana plug patch cords directly from AST Labs last week and added some Kelvin leads since I was already paying for shipping, even though I don't have a 4 wire meter just yet.  The quality looks better than what I've seen from typical AliExpress vendors, but unsurprisingly doesn't match what I've ordered from Probemaster.  The leads are nice and flexible, appear to be silicone.  The clamps are made of what feels like a cheap plastic, but the clamping action feels solid.  The actual alligator clips on the clamp look solid and have good alignment on the teeth.  I just verified they are fully isolated up to the actual teeth, the spring is insulated from the terminals.  For around $20, I think it was a good deal.

I got these from Banggood and they work fine : https://www.banggood.com/Y238-2Pcs-LCR-Bridge-Test-Cable-Universal-Digital-Multimeter-Plug-Milliohm-Test-Line-Test-Clips-p-1482576.html?imageAb=2&rmmds=myorder&cur_warehouse=CN

These beautiful clips seem to belong to Tonghui. I think somewhere else should be the same ending bananas.
