一、测量方法依据ＪＪＧ99— 90砝码检定规程 ,以一等 2 0 0 ｇ砝码检定二等 2 0 0 ｇ砝码为例。检定过程采用单次替代衡量法 ,两人各检一次 ,具体操作如下 :在 2 0 0 ｇ○Ⅰ3 级天平上 ,将标准砝码ｍＢ 放在天平右侧盘内 ,在左侧盘内放入替代砝码ｍＴ,读取平衡位置ＬＢ,然后取 First, the measurement method based on JJG99-90 weight test procedures, with first-class 200 g weight test second 200 g weight as an example. The calibration process using a single alternative measure, the two seized once, the specific operation is as follows: 200g ○ Ⅰ level 3 balance, the standard weight mB on the right side of the balance plate, into the left side of the plate Replace the weight mT, read the equilibrium position LB, and then take
