OIML R 76 is a recommendation file of non-automatic weighing instruments (NAWI), which is widely accepted by member countries. As an instrument for trade using, NAWI is known intimately and easy to judge weighing correct. In OIML R 76, there are E0, Eand Ec, usually Ecis as the final error compared with maximum permitted error, Ec=E−E0, which are complex concepts; but in fundamental ideas, error looks simply, which is equal to difference value of indicating value and standard value. The error model is the central issue discussed and studied in this paper, aiming to propose a modified error calculation method that harmonises theory with practical application. |
