有数种接触式端度计量仪器的示值误差用标准量块以连续配对法(以下简称配对法)检定,以减少标准量块误差对检定结果的影响。但配对法检定的可靠性还与受检仪器在误差方面的特点——系统误差和偶然误差的分配状况有关,在考虑是否选用配对法及选择标准量块和配对对数时,应该注意这一点。一、配对法原理设配对量块的实际尺寸(证书给出)为L_0、L_1、……、L_n,配成 h 对检定时仪器上相应的读
There are several kinds of contact end of the meter indication error with the standard block with continuous matching method (hereinafter referred to as the pairing method) test to reduce the error of the standard measuring block test results. However, the reliability of the paired test is also related to the error characteristics of the equipment under test - systematic errors and the distribution of contingent errors. It should be noted when considering whether to use the pairing method and to select the standard block and paired logarithm . First, the principle of matching law Suppose the actual size with the measurement block (certificate given) L_0, L_1, ......, L_n, allocated h on the test instrument when the corresponding read
