I was wondering if it would be useful to make a plug in adapter for multimeters. It just gave me a change battery sign and I measured it at 9.0V and 9.1V on 2 meters and the new battery is 12.8V.
Would that not throw alot of error into measurements? It didnt seem to. I making a big deal out of something the designers already covered? Would a regulated 7812 based supply introduce more noise and thereby throw off accuracy moreso?
