Solartron 7081 Test Leads
For the Kelvin clips, your best bet is a set of HP kelvin clips (I forget the part number... they run around 200 bucks). They use the old ESI style clips that use rubber o-rings as springs to close the clips.
Next best is Ebay Chinese clips... they have a metal spring that can add some capacitance that affects high freq AC measurements. They are only a few dollars and actually work pretty well.
I think these work pretty well too, glue some coppersheet between the
jaws. Solder the wires to the copper (befor glueing ;-) ) And you have a
nice and cheap Kelvin clip. They are also available in childerens size
so you can make a SMD version too :-)
See the link, because I do not know the english word. (you use them to
clip laundry to the line when it hangs to dry)

I hate the only talk and no action things so I named the clothes pin and
tried it myself. It works great :-)
Picture: http://www.pa4tim.nl/?p=2604
The text is Dutch but I will tell. The pins are a bit flimsy but had a
nice size. They look real thik and solid but it's just an U-profile. So
I filled that up with hotglue (if they turn out to be not to sturdy I
make new ones and fill them with epoxy) after that I put shrink tubing
over it to give it a nice look and more grip. The contacts are made from
copper rivettes. A piece if silverwire as short as possible gave a
0,0003 ohm display (with a cold meter) so I think that is pretty neat.

My only excuses are that:
- I am on vacation this week.
- I have not received the DMM yet.
- I have not received the connectors yet.
However, once I get home, get the items and one of those round TUIT's, I'll
'gitter done'.
