WebFeb 15, 2024 · When adhering to USP Chapter 41, where the coverage factor is specified to be 2 and the required tolerance is 0.10%, the minimum weight formula simplifies to: Min Wt = 2000 * sd. To satisfy the tolerance requirements, the smallest net weight to be used on a particular weighing instrument must be greater than or equal to the minimum weight. WebIn short, using the premise that users need only two weights to test an individual balance, the following tests and weights are recommended: 1. Sensitivity, preferably with the large weight (100% of nominal capacity). 2. Repeatability, with the small weight (approximately 5%- 10% of nominal capacity). 3.
