检定测量范围大于300mm的游标高度尺,在没有专用量块的情况下,可用83块组,8块组或5块组的4等量块及一米的测长机,对其示值误差进行检定。现将检定方法介绍如下: 以分度值为0.05mm测量范围为0～1500mm的游标高度尺为例。取受检点为751.2mm。如图所示,将高度尺1调至751.2mm,同时将内径千分尺2也调至751.2mm(含块 Test the measurement range greater than 300mm vernier height ruler, in the absence of special amount of block, available 83 blocks, 8 blocks or 5 blocks of 4 equal blocks and one meter length measuring machine, its indication error Test. Now test methods are described below: Take the scale of 0.05mm measuring range of 0 ~ 1500mm cursor height gauge as an example. Take the checkpoint for the 751.2mm. As shown, the height gauge 1 transferred to 751.2mm, while the diameter micrometer 2 is also adjusted to 751.2mm (containing block
