From ericp at snf.stanford.edu Sat Apr 21 19:07:02 2007 From: ericp at snf.stanford.edu (ericp at snf.stanford.edu) Date: Sat, 21 Apr 2007 19:07:02 -0700 Subject: Problem tylan3 SNF 2007-04-21 19:07:01: TEMPC wrong Message-ID: Jim Kruger reported a ~25% thicker oxide than predicted, at first blaming my calculator :^) I checked this tube: In IDLE, where the SP's are all 800C, TEMPC is indicating 800C, but driving at 25-100% SCR. The outder zones are sitting at 850-900C, driving at 0. This likely indicates that the center zone temperature measurement is off. (This is all in steady state).
