当前,国内许多量具生产厂出口公英制(或英制)游标卡尺,对英制游标卡尺示值误差的检定,国内尚无统一的检定方法,也无检定示值误差的英制专用量块,再加上多数职工对英制不熟悉,因此各量具厂在检定英制卡尺示值误差时很不统一,有的检定过程过于繁琐。现根据英制游标卡尺的读数原理并参照了GB1214—85(国家标准),拟订了采用常用的卡尺专用量块(以mm为单位)检定英制卡尺示值误差的方法。该方法经实践使用,颇受检验人员和商检部门的欢迎。现将游标读数值为1/1000in和1/128in的两种英制游标卡尺示
At present, many gauges manufacturers export metric (or English) calipers, the British caliper caliper error of the test, there is no uniform verification method, there is no test indication error in English special block, together with the majority of workers Not familiar with the British system, the measuring tool factory in the verification of British caliper error is not uniform, some of the verification process is too complicated. Now according to the British vernier caliper reading principle and with reference to GB1214-85 (national standards), developed by the commonly used special caliper block (in mm units) verification of British caliper error indication method. The method used by practice, quite popular with inspectors and inspection departments. Now read the value of the cursor 1 / 1000in and 1 / 128in two British vernier caliper shows
