在秤上加或卸标准砝码是可动式不等臂秤检定和调整过程中最费力的操作。例如,检定一台最大称量为150公斤的标尺秤,需要在0.8～1.0米的距离上搬动总量为520公斤的砝码;调整秤时,这个量还要增加几倍,因为在标尺的极限点上加或卸砝码需要进行2～3次。检定大载荷秤时,体力的耗费 Adding or removing standard weights on the scales is the most laborious operation during the verification and adjustment of the movable arm scales. For example, checking a scale that weighs up to 150 kg requires moving a total weight of 520 kg over a distance of 0.8 to 1.0 meters; when adjusting the scale, the amount increases a few times, The limit point plus or unloading weight need to be 2 to 3 times.
