That's what statistics promises for a large collection of *independent* events. A bunch of resistors bought at the same time, possibly from the same production run are not independent. Of course different values and different types make them likely to be less dependent. Overall, I would find it surprising if all resistors in the kit were truly low. So much so that I suspect a different explaination. To me the most obvious explaination is your ohmmeter. I know you said it was a good instrument, but what is it's published tolerance? How long has it been since it was last calibrated? If you have a resistance standard availble, try measuring that. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
