This paper presents two mechanisms for load cell calibrations. The first technique was to use deadweight to generate the required reference load (Applied load). The second method was to use a pressure piston gauge to generate the required calibration force. In both mechanisms, the setup and procedures are described. For verification the results of these methods were compared with international metrology institute calibration results. It was found that deadweight method is the most accurate and the piston gauge is the most realistic at high force values.

用静重和压力活塞计进行力校准的技术研究

本文介绍了两种称重传感器校准机制。第一种技术是使用自重来生成所需的参考载荷（Applied load）。第二种方法是使用压力活塞计来产生所需的校准力。在这两种机制中，都描述了设置和程序。为了验证，将这些方法的结果与国际计量机构的校准结果进行了比较。发现自重法最准确，活塞量规在高力值下最真实。
