Check the catalogs, Matthias. Somebody specified a standard type. BTW, what temprature are you controlling at? You only need it on the graph around that point, you know. Here's a messer talking. The engineer in you will want it on the graph from absolute zero up; Be a messer - it's easier ;-). -- Regards, Declan Moriarty. -- Author: Declan Moriarty INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB CHIPDIR-L (or the name of mailing list you want to be removed from).
