在对AGT—5(10)型案秤进行十分之一秤量四角检定时,往往出现这样的情况:如果砝码放在盘子前部(图1)误差是正的,那么砝码放在盘子后部时,误差一定是负的。反之亦然,即如果前者是负差,那么后者一定是正差。为什么重物在秤盘前、后部的误差会出现这种两极性?如何进行调整?怎样根据前后误差的大小和正负来确定调整量?本文对这些问题作一分析。 When weighing the AGT-5 (10) scale ten-tenths of a square, it is often the case that if the weight is placed on the front of the plate (Figure 1) the error is positive then the weight is placed behind the plate Ministry, the error must be negative. Vice versa, that is, if the former is negative, then the latter must be positive. Why weight in the pan before and after the error will appear this kind of polarization? How to adjust? How to determine the amount of adjustment according to the size of the error before and after? The paper analyzes these problems.
