I have a 2003 Tbolt , that shows and updates the temperature constantly.
And the "yellow temp graph" is "natural".
The 2004& 2005's does rarely update , and the graph jumps 4 x 250mC , in
one jump like a Schmitt-Trigger.
I'm quite sure i read that someone here on the list had a "reel" of the
old good sensors , but i can't seem to find the posting.
Any hints

CFO,
Googling "DS1620 site:febo.com" should give you the relevant details.
And I bought some chips from French eBay seller philing2003. His chips
are rev D1 and work fine. Rev E chips produce staircase-looking curves
because Maxim changed the high-res temperature protocol while Trimble
didn't adapt.
