Abstract :
This paper is an attempt to put into a few words a process that has taken a long time to prove and put into practice and is still being proven as time goes on. The goal of high product quality should be a never ending process, almost by definition, and in todays world of affordable high precision in is ever more important to keep on top of the production process to ensure the final product meets the design goals. The subject of this paper is the calibrating of the highest precision multifunction calibrator and the challenge of supporting its´ accuracy and proving of the process by which it is being done, together with a look at a similar process verifying an essentially manual device, a precision AC/DC transfer device
