Subject: Uncertainty in Cal and Testing RE26 Date: Fri, 19 Feb 1999 14:50:14 -0500 (EST) From: Bruce Mayfield To: iso25@fasor.com Subject: Re: Re24: Uncertainty in Cal and Testing (fwd) I have been reading along in this last fracus on uncertaintly calcualations, freeware software usage and measurement unceratinty for some time. Lets not forget one point. What ever process that is used has to be simple, efficient, easy to use.. defined as, someone with a two year degree in electronics ( there is no more military PMEL training, besides they did not address this subject anyway). It cannot take hours to perform. Our future employees will come to use with no Metrology training and no experince in the field. Uncertaintly calcualations have to be ecominically viable, if they are not, as much as we talk about uncertainty calculations they will not happen. Business exists to satisify the customer requirements without adding cost or options that are not required or requested. Especially ones that seem to add know apparent value. The unlearned ( corporate management, purchasing agents, buyers the decision makers) are the ones that ultimately will determine how successful measurement uncertainty calculations are implemented. They are the ones that sign the checks that drive use. I do not know how successfull you have been in finding someone with a 4 your degree in electronics, science and math that wants to work as a technician at technician pay. I know I have not been able to find one. We have to be practical in our demands and requirements. Whether the calculations are performed inclusive in a calibration software application ( 1st choice) or a free standing program that leads someone with know real background in fast fourier transformation calculations ;)) to arrive at a solution to the uncertaintly question, the answer has to be ecominically viable and esy to use. He who builds the better mouse trap ( uncertainty software appliaction) will have a large path leading to his door. PS, Don't get me wrong, I truely believe that measurement uncertainty is important to know and understand. Bruce Mayfield Telogy
