I think we need to hear what the functions of the software are. I am assuming that if it is doing calculations, it is doing things like R&R studies, linearity plots, stability charts, and bias studies. These things are all simply mathematical functions! Are RAB approved calibration labs the only ones with the demonstrated ability to do math? I think not. I have never received a calibration certificate that includes any of the above statistical information. The fact of the matter is, I can verify function of software using completely fictional gage data by verifying the results using math!
