D value in weighing balance
WebA precision balance is an accurate, robust weighing instrument with capacities from 120 g to 64 kg, and readabilities from 1 g to 0.1 mg. Lower readability models have a draft shield to ensure the best performance, while high-capacity models have a large weighing pan to accommodate heavy loads. WebJul 9, 2024 · If the standard deviation obtained is less than 0,41 d, where d is the readability of the instrument tested, the value should be replaced by 0,41 d. In such case, the repeatability is satisfactory if two times 0,41 d divided by the desired smallest net weight does not exceed 0,10%.

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. WebBalances, Scales and Weighing Laboratory balances are used to accurately determine the mass or weight of an item or substance within a specific weight range and to a particular readability. They are typically used to measure the weight of smaller amounts of substances in grams, milligrams, or micrograms.
