Ih. Lira et W. Woger, THE EVALUATION OF STANDARD UNCERTAINTY IN THE PRESENCE OF LIMITED RESOLUTION OF INDICATING DEVICES, Measurement science & technology, 8(4), 1997, pp. 441-443
Since the type A evaluation of standard uncertainty according to the r
ules given in the ISO Guide to the Expression of Uncertainty in Measur
ement does not take into account the uncertainty that arises from the
limited resolution of indicating devices, we show in this design note
that the treatment of this problem calls for a quantity about which no
statistical information is available; therefore, its uncertainty has
to be derived from a type B evaluation.
