I read a Fluke report on the development of their JJ array. In it they pretty much debunked the accumulated wisdom of low thermal wiring. Their testing showed that one had to empirically determine the best wiring for the application. They wound up using a plated, stranded wire... the exact opposite of what conventional wisdom would dictate. ------------------ One other point, how many people truly think about the wire and the connections ? These add more error then any of the equipment I mentioned. Damn few binding posts are even worth considering for real work, but no one considers that either. For serious work those laboratory gold plated beryllium-copper cables are very expensive. How many people have those laying around ? Not many ! _________________________________________________________________ Hotmail: Trusted email with Microsoft's powerful SPAM protection. http://clk.atdmt.com/GBL/go/177141664/direct/01/ http://clk.atdmt.com/GBL/go/177141664/direct/01/

Mark, I read, some time past admittedly, Flukes description of their array system and do not remember them debunking any such thing. Even the JJ has thermal junctions that have to be considered when attaching to it, especially considering the extreme temperature. So, perhaps the debunking you are referring to has to do with the actual connection to that extremely cold surface. In no way does that debunk accumulated wisdom for a normal environment.
