I looked up the cells I have and they show a max of 122F. My Calibrated = Thumb might consider that a bit warm, I'll double check via IR. Thanks for the info!

If you know who made the cells, you can check the mfgr's sheet for max = temp. That varies quite a lot. Panasonic goes as high as 140F, some as low as = 104F. Calibrated Thumb isn't the way to go here. I also use an IR thermometer, and/or thermocouple. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
