> Could someone please help me? I think Dom has hit the nail on the head. Your input is climbing because t= here is no pull-down resistor. Most meters have a characteristic resistanc= e of 10MEG. Try putting a 10M resistance directly across the input. = =20 --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
