一、现有的检定方法及缺陷按照JJG455-2000《工作测力仪检定规程》的规定,根据测力仪的规格选用相应量程的标准测力砝码、标准测力仪、标准测力杠杆、材料试验机或力标准机作为力标准器进行测试和检定。使用标准测力砝码、标准测力仪、标准测力杠杆等进行测试时,容易引起较大误差,同时也无法满足国家检定规程进行侧向检定。而使用材料试验机或力标准机进行测 First, the existing test methods and defects in accordance with the provisions of JJG455-2000 “working dynamometer verification rules”, according to the specifications of the dynamometer choose the appropriate range of standard load-bearing weights, standard dynamometer, standard force lever, Material testing machine or force standard machine as a force standard for testing and verification. The use of standard load cell, the standard dynamometer, the standard force lever test, easily lead to greater error, but also can not meet the national test procedures for lateral verification. The use of material testing machine or force standard machine to measure
