一、前言标准杠杆过去主要作为标准杠杆试验机的标准。但近年来,开始用它来检查汽车衡之类的大型秤。目前正在研究用标准传感器来检定大衡器的方法,看来很有希望。但是,如何对标准传感器进行检定?还没有解决。有人提出可以用标准杠杆来检定。因此杠杆的用途又有扩 First, the foreword Standard leverage in the past mainly as a standard lever test machine standards. But in recent years, began to use it to check the scale such as truck scale. It is hopeful that research is currently underway on the use of standard sensors to verify large scales. However, how to calibrate the standard sensor has not been solved yet. Someone suggested that you can use the standard lever to test. Therefore, the use of leverage has expanded
