Sensitivity. Sensitivity (i.e., systematic deviation) is The important thing parameter (In addition to repeatability) that ought to be assessed periodically. At the upper conclusion on the weighing selection, the sensitivity and eccentricity come to be the dominant contributors to the overall measurement uncertainty. The top quality in the weighing vary is As a result The best place to carry out these schedule checks. Figure 1 Evidently displays that the sensitivity ingredient of uncertainty (pink line, U_SE) is a completely horizontal line, which suggests it may be safely and securely assumed that if the sensitivity measurement is carried out within the high end from the weighing array, The end result signifies The full of your nominal capability on the balance, providing the weigh mobile is working accurately.
