Assuming that the calibration is in tolerance (error bars less than the blue tolerance lines). Would the example method below for determining uncertainty of the device at calibration be appropriate? I assume the calibration tolerance +/-2% is a rectangular probability distribution and therefore...
Hi thanks for replying. I am familiar with the usual Test Uncertainty Ratio of 4:1. In the example I attached, the error bars representing calibration uncertainty are much smaller in magnitude compared to the calibration tolerance of the UUT. It's not quite clear from the image but I suspect 4:1...
I'm researching uncertainty calculations based on the GUM method. I have a question about estimating the standard uncertainty of an instrument based on it's calibration. In the examples I have seen, a manufacturer will quote a certain reference accuracy and state the statistical significance...
