My only excuses are that:

1.  I am on vacation this week.
2.  I have not received the DMM yet.
3.  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'.

:-)

I hate the only talk and no action things so I named the clothes pin and
tried it myself. It works great :-)

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.

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.
