    摘要: An electronic balance weighs one and the same load of an arbitrary amount repeatedly in a serial test from which it determines a statistical quantity, preferably the standard deviation. Based on this determination, it is possible to state the uncertainty of subsequent measurements at the actual location. It is advantageous to use as the test load the weighing sample itself, so that its effect on the random errors will be included in the uncertainty. When the uncertainty at a given confidence level is defined as a requirement, then the result of the test may serve to determine the minimum allowable sample weight.
