D value in weighing balance
The “d” value, according to the U.S. National Institute of Standards and Technology (NIST) Handbook 44, is a scale’s smallest standard displayed division. That value is equivalent to a non-approved scale’s readability. As an example, for Adam’s HCB 103aM (one of our Highland approved precision balances), the “d” … See more We’ve covered trade-approved scales before in our Quick Guide to Trade Approved Scales and Balancesblog. Trade-approved – also called legal-for-trade – essentially means that the weighing device was tested and meets … See more If you’re using the weighing results to set a price by weight, you need to use the “e” value. That value is the resolution that a legal-for-trade scale … See more In the U.S., scales that are approved for trade typically are Class II or Class III. The legal cannabis industry requires the use of Class II scales (which … See more The “e” value is the verification scale interval, which means the smallest scale increment that can be used to determine price by weight in commercial transactions. That … See more 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.

A precision balance on the other hand typically measures to the nearest 0.1-0.01g but has higher capacity. Both can measure capacities from hundreds of grams to kilograms.
WebDec 26, 2024 · To calculate dimensional (DIM) weight, multiply the length, width, and height of a package, using the longest point on each side. Then, divide the cubic size of the package in inches by the DIM divisor to calculate the dimensional weight in pounds. Note: For non-square packages, you would take the longest dimension on each side and round up. WebApr 11, 2024 · Due to the sensitivity of the high-performance weighing cell, analytical balances are fitted with a draft shield to ensure a stable weighing environment.
