摘要
介绍了数字压力计的分类和原理,并以活塞式压力计为计量标准,详述了工作标准数字压力计的检定项目和方法,重点强调了周期稳定性、示值误差检定和高度差修正的原则和方法.同时,阐述了测量结果不确定度评定的过程和方法,为工作标准数字压力计的检定工作提供了指导.
Abstract
The classification and principle of digital manometers are introduced,and the calibration items and methods of working standard digital manometers are detailed with piston manometers as the measurement standard,with emphasis on the principles and methods of cycle stability,demonstration value error calibration and height difference correction.At the same time,the process and method of uncertainty assessment of measurement results are described to provide guidance for the calibration of working standard digital manometers.
