用千分尺校对内径百分表１前言内径百分表，是通过比较测量的方法进行的，因而必须在测量孔径前具有作为校对“零位”的标准。光面环规作为校对内径百分表“零位”的标准是大家所熟知的，然而更多的情况是利用千分尺作为校对内径百分表“零位”的标准，尤其是对于较大尺寸... Calibrating an ID Dial Indicator with a Micrometer 1 Introduction ID meters are measured by comparative methods and therefore have to be calibrated “zero” before the measurement aperture. The glossy ring gauge is well known as a standard to calibrate the “zero” of the inner diameter dial gauge, but more often it is the use of a micrometer to calibrate the “zero” of the inner diameter dial indicator, especially for larger sizes. ..
