在翻阅检定记录时,发现在用精 密压力表检定普通压力表时标准指 针指到整数格,而去读被检表的格 数,这样估读误差和视差都很大,因 为当被测量的偏移量很小时,在被检 表上基本上显示不出来,没有充分利 用标准表的精度。检定的目的是确定 被检表的精度。我们如改为把被检表的指针 When looking through the verification records, it was found that when using a precision manometer to check the ordinary manometer, the standard pointer refers to the integer cell and the number of cells to be examined is read, so the estimation error and the parallax are large, because when the measured partial When the amount of shift is very small, basically not show up on the seized table, did not make full use of the accuracy of the standard table. The purpose of verification is to determine the accuracy of the seized table. We are like the pointer to be seized table
