在没有大尺寸量块的条件下,检定500毫米以上的大型游标卡尺,可以因陋就简地用小尺寸量块配合大型千分尺调整棒对大型游标卡尺进行检定。仅以500毫米游标卡尺为例。可用尺寸为81.10、161.30、241.40毫米的三级量块的量块组去检定游标卡尺的81.10、161.30、241.40毫米的三个尺寸。用尺寸为21.6、1.70和6.9毫米的三级量块的量块 In the absence of large-size block under the conditions of the test more than 500 mm large vernier caliper, you can simply because of the small size of the block with a large micrometer adjustment of the large vernier caliper test. Take a 500mm vernier caliper as an example. Available size 81.10,161.30,241.40 mm three-level block of measuring block to determine the Vernier caliper of 81.10,161.30,241.40 mm three dimensions. A block of three-level gauge with dimensions of 21.6, 1.70 and 6.9 mm
