Mathematically Analysis of Measurement Instrumentation on the test benches at DLR/Lampoldshausen [PDF]
, 2014 To appraise the quality of measurements of a test bench, different statistical methods can be used. Two statistical methods are described in this paper, the classical Gaussian error propagation and the general uncertainty method (GUM). We will show how these statistical methods can be used to give a reliable indication of the quality of the ...
