Consider that the instrument is used 20 months after calibration to measure on its 1 V range a potential difference V, and the arithmetic mean of a number of independent repeated observations of V is found to be V = 0,928 571 V with a Type A standard uncertainty u(V ) = 12 μV. One can obtain the standard uncertainty associated with the manufacturer's specifications from a Type B evaluation by assuming that the stated accuracy provides symmetric bounds to an additive correction to V, ΔV, of expectation equal to zero and with equal probability of lying anywhere within the bounds. The half-width a of the symmetric rectangular distribution of possible values of ΔV is then a = (14 × 10−6) × (0,928 571 V) + (2 × 10−6) × (1 V) = 15 μV, and from Equation (7), u 2(ΔV ) = 75 μV2 and u(ΔV ) = 8,7 μV. The estimate of the value of the measurand V, for simplicity denoted by the same symbol V, is given by V = V + ΔV = 0,928 571 V. correlations c_correlation 0 c_correlation 0 c_correlation 0 c_correlation 0 0
