在地秤实物检定时,经常遇到这样一个问题:当检定到最大秤量时地秤超差,调整符合要求后回检零点,却变了几公斤至几十公斤(因调整量的大小而异),又需要重新调整。对地秤最大秤量一次过调整的方法有三种,第一种是用常数0.8预测零点变化量的方法。但因地秤型号和称量不同,用0.8常数很难预测到一切地秤的零点变化量完全达到一致,因此其准确性大约只能达到80％;第二种方法是检定器倍数法。由于用小砝码代替大的标准砝码,即使代替的精度很高,杠杆在重荷下可能变形,准确性也会受到影响;第三种是大浮砣至支点刀刃实际长度的调整法。本文将对该方法作详细介绍。调整方法是:首先用钢直尺确定大游砣中
Physical testing in the scale, often encounter such a problem: when the maximum weight test when the scale overweight, adjusted to meet the requirements after the check zero, but changed a few kilograms to tens of kilograms (due to the size of the adjustment varies ), But also need to re-adjust. There are three ways to weigh the scale at one time. The first one is to use the constant 0.8 to predict the variation of the zero point. However, due to the scale model and weigh different, with the 0.8 constant is difficult to predict all zerosting zero changes completely consistent, so its accuracy can only reach about 80%; The second method is the detector multiple method. As the replacement of large standard weights with small weights, even if the replacement of high precision, the lever under heavy load may be deformed, the accuracy will be affected; the third is the large float to the fulcrum edge of the actual length of the adjustment method. This article will detail the method. Adjustment method is: First, use the steel ruler to determine the tour Yau
