     被校压力表和标准压力表 然后 比较 两种压力表 的指示数值。 The so-called calibration is to pass the same pressure in the calibrated pressure gauge and the standard pressure gauge , and then compare the indicated values of the two pressure gauges . 所选择的标准表的绝对误差应 小于被校仪表 绝对误差的1/3 ,所以它的误差可以忽略, 因此 认为标准表的读数就是真实压力表的数值。 Because the absolute error of the standard gauge generally selected should be less than 1/3 of the absolute error of the calibrated instrument , its error can be ignored. Therefore , the reading of the standard gauge is considered to be the value of the real pressure gauge . 仪表对于标准仪表的读数误差, 小于或者等于 被校仪表的规定误差,则 可以 认为被校仪表合格。 If the calibrated meter's reading error to the standard meter is less than or equal to the specified error of the calibrated meter, the calibrated meter can be considered qualified.
