电子吊秤周期检定方法探讨
|
摘要
目前,国内检定电子吊秤的主要方法是将标准砝码作为标准器。在电子吊秤的工作环境或专业的检定环境中,按照JJG 539—1997《数字指示秤》检定规程检定。这项工作强度大,人员工作效率低,需要用到较多的辅助设备。简要介绍了使用叠加式力标准机作为标准器检定电子吊秤的情况,在满足准确度等级要求的前提下,使用辅助设备完成电子吊秤旋转试验和鉴别力试验,进而高效、方便地完成电子吊秤的检定工作,大大节约了标准器的成本。
At present, the main method in the verification of electronic steelyard is the standard weight as standard. In electronic hanging scale work environment or professional verification environment, according to JJG 539-1997 "Digital Indicate Scales" verification regulation of verification. This work is of great strength, low efficiency; need to use more auxiliary equipment. Are briefly introduced in this paper the use of overlap type force standard machine as a test of a standard electronic hanging scale, in under the premise of satisfying the accuracy class requirements, the use of auxiliary equipment to complete the electronic Hanging Scale rotation test and discrimination test, then, and conveniently complete electronic hanging scale inspection work, greatly saves the cost of standard.
