自一九七五年以来,我校工厂试制和小批量生产了商用电子计价秤。其中机械秤体的称量精度都达到最大称量的二千分之一(最大称量为十市斤,误差都在半钱以内)。这个精度在自动秤来说是比较高的。本文拟就提高称量精度的问题进行一些讨论。 Since 1975, our factory has trial-produced and small-batch commercial electronic scale. Wherein, the weighing accuracy of the mechanical scale body reaches the one-thousandth of the maximum weighing (the maximum weight is ten kilos, the error is less than half the money). This accuracy is higher in the automatic scale. This article intends to raise the issue of weighing accuracy for some discussion.
