一、概述1.测量依据本仪器是由测力传感器测量值与探测杆截面积相除换算成压强的,因此可参考JJG455-2000《工作测力仪检定规程》对力传感器测量。2.测量标准F2等级标准砝码,出厂编号206,JJG99-2006《砝码检定规程》中给出20kg砝码的扩展不确定度不大于100mg,包含因子k=2。3.环境条件温度为(20±2)℃,相对湿度≤75%。4.测量对象土壤紧实度仪型号TJSD-750,浙江托普仪器有限
I. Overview 1. Measurement Basis The instrument is measured by the force sensor and the probe rod cross-sectional area is divided into pressure, so refer to JJG455-2000 “working dynamometer verification procedures” on the force sensor measurements. 2. Measurement standards F2 grade standard weight, factory number 206, JJG99-2006 “weight test procedures” given 20kg weight expansion uncertainty is not greater than 100mg, including the factor k = 2.3 Environmental conditions Temperature (20 ± 2) ℃, relative humidity ≤ 75%. 4. Measuring object Soil Compactness Tester Model TJSD-750, Zhejiang Top Instrument Limited
