随着数字技术和传感器技术在仪器仪表中的普遍应用,越来越多的计量技术机构选用数字压力计作为计量标准器具开展量值传递工作。由于数字压力计显示位数较多,按照标准源法进行检定较困难,因此在实际工作中通常选用标准表法完成检定任务。为确保数值记录准确,证书符合检定规程要求,现结合JJG52-1999《弹簧管式一般压力表、压力真空表和真
With the universal application of digital technology and sensor technology in instrumentation, more and more metrology institutes choose to use digital pressure gauges as measurement standards to conduct value transmission. As digital pressure gauge display more digits, according to the standard source method for verification is more difficult, so the actual work is usually selected standard table method to complete the verification task. To ensure the accuracy of numerical records, certificates meet the requirements of test procedures, are now combined with JJG52-1999 "spring tube general pressure gauge, vacuum gauge and vacuum
