WebWeighing is one of the most common, yet critical and time consuming, tasks undertaken in the laboratory; therefore, weighing the right way is crucial. Balances have developed to the point that, in general, they provide accurate results in most lab environments, with the possible exception of ultra-micro balances. 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.
