Quite so. I'm suggesting that the temp "bloom" as full-chg is reached would be easier to detect at fractional C if T is allowed to rise somewhat more than it otherwise would, Tmax < spec. It's possible that dV/dT would be similarly affected. regards, Jack -- http://www.piclist.com#nomail Going offline?
