D value in weighing balance
WebIn order to test a balance’s accuracy, Chapter 41 requires you to use a test weight that has a mass between 5% to 100% of the balance’s maximum capacity. How do I calculate it? The measurement uncertainty of a weight must be ≤ 1/3 of 0.10%. Perform one measurement using a test weight with a mass between 5% to 100% of the balance’s capacity. WebPlace a single weight that weighs about 1/3 to 1/2 of the balance weighing capacity successively in the positions shown in Figure 1 (center, right-front, right-rear, left-rear, left-front, and center) and record the measurement value at each position.
