Các bản vẽ kỹ thuật để chế tạo là sản phẩm cuối cùng của khâu thiết kế. Chúng phải thỏa mãn hai mục đích: bao gồm đầy đủ tất cả các thông tin cần thiết để chế tạo và cũng còn là một tiêu chí kiểm soát kỹ thuật đối với các mức độ sửa chữa. Trước cuối thế kỷ 20, rất nhiều bản vẽ kỹ thuật được thực hiện bằng tay với sự trợ giúp của bảng vẽ cơ khí. Sự ra đời của máy tính với giao diện người dùng đồ họa đã có thể giúp thực hiện. | Appendix D - Definitions Handbook 44 - 2007 meter register. An observation index for the cumulative reading of the gas flow through the meter. In addition there are one or two proving circles in which one revolution of the test hand represents 1 2 5 or 10 cubic feet or or cubic meter depending on meter size. If two proving circles are present the circle representing the smallest volume per revolution is referred to as the leak-test circle. metrological integrity of a device . The design features operation installation or use of a device that facilitates 1 the accuracy and validity of a measurement or transaction 2 compliance of the device with weights and measures requirements or 3 the suitability of the device for a given application. Added 1993 minimum capacity. The smallest load that may be accurately weighed. The weighing results may be subject to excessive error if used below this value. Added 1999 minimum clear interval. The shortest distance between adjacent graduations when the graduations are not parallel. Also see clear interval. b minimum delivery. The least amount of weight that is to be delivered as a single weighment by a belt-conveyor scale system in normal use. minimum tolerance. Minimum tolerances are the smallest tolerance values that can be applied to a scale. Minimum tolerances are determined on the basis of the value of the minimum graduated interval or the nominal or reading face capacity of the scale. See also definition for basic tolerances. minimum totalized load. The least amount of weight for which the scale is considered to be performing accurately. moisture content wet basis . The mass of water in a grain or seed sample determined by the reference method divided by the mass of the grain or seed sample expressed as a percentage . a b money-operated type. A device designed to be released for service by
