Abstract
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.
