I guess that's why a $200 Simpson 260-8 analog VOM (specs at http://www.simpsonelectric.com/uploads/File/datasheets/2608.pdf ) has 2% DC accuracy and 3% AC accuracy, while a $200 Fluke 177 digital VOM (quick specs at http://us.fluke.com/usen/products/specifications.htm?cs_id=29983(FlukeProducts)&category=HMA(FlukeProducts) or detailed specs in the user manual at http://assets.fluke.com/manuals/175_____umeng0000.pdf ) has a DC accuracy of 0.15% + 2 counts and an AC accuracy of 2% + 3 counts. > I know they show a nice precise number, but that number was derived > from the same electrical sensiing package, Sometimes true. > then through an analog to digital converter. True for a digital meter. That number is then simply displayed directly, instead of run through a mechanical device and left to the user to interpolate on a scale. Matt Roberds
