Sensitivity. Sensitivity (i.e., systematic deviation) is The crucial element parameter (Other than repeatability) that needs to be assessed periodically. At the upper conclusion of the weighing vary, the sensitivity and eccentricity turn into the dominant contributors to the overall measurement uncertainty. The high-end with the weighing variety is Hence The perfect destination to perform these plan checks. Figure 1 clearly demonstrates that the sensitivity element of uncertainty (pink line, U_SE) is a totally horizontal line, meaning it can be properly assumed that In the event the sensitivity measurement is performed for the top end from the weighing variety, the result represents The full on the nominal capacity on the balance, supplying that the weigh mobile is Operating the right way.
