3 terminology and units of measurement

3.1 Terms As used in this specification, the term is consistent with JJF 1181-2007 "metrological terminology and definitions", in order to Easy to use, easy to understand, especially references to some of the terms, and added some special terms apply to this specification. 3.1.1 Dynamic (mine) light rail scale weighinginstrumentsforminingcarinmotion In mining light rail line used to mine the quality or the quality of the vehicle train vehicles automatic weighing scales. NOTE. This term is often referred to in the industry dynamic automatic light rail scale. 3.1.2 conventional true value conventionaltruevalue For a given purpose and with the appropriate degree of uncertainty, given the specific amount of the agreed value acceptable. Note. This specification refers to a specific amount of static reference vehicle quality. 3.1.3 Weighing area weighzone Area and cited by the rail carrier at both ends of the composition, is called when weighing the vehicle must be in this area. 3.1.4 lead track apron Part of the weighing area, located at both ends of the carrier, but does not include a carrier. 3.1.5 maximum capacity (Max) maximumcapacity (Max) Excluding the largest weighing the ability to add tare to represent the symbol Max. NOTE. Dynamic maximum capacity light rail scale refers to the light rail scale can be dynamically and without weighing the accumulated maximum load. 3.1.6 minimum capacity (Min) minimumcapacity (Min) When the load is less than the value of the weighing result will be too large relative error, the load value is called the minimum capacity in order to meet No. Min representation. 3.1.7 Dynamic scale interval (d) dynamicscaleinterval (d) Value expressed in units of mass of dynamic weighing, display equal to the difference between two values shown or printed adjacent.
