The measurement is carried out under two states of fastening and loosening of the frame fastening screw, no matter whether the frame is fastened or not, the contact between the measuring surface of the measuring jaw and the surface of the gauge block can normally slide, and a micro-motion device is used during the contact. The error of each point indication value is determined by the difference between the reading value and the size of the gauge block.
When checking, the gauge block is placed on the flat plate with the smallest section and is not fixed, in the measuring process of the gauge block by the height-adjusting caliper, the gauge block is extremely easy to be stressed and move or fall down, the checking efficiency is low, the collision between the falling gauge block and the flat plate can lead to deformation of the flat plate and the gauge block, checking errors are caused, and if the flat plate and the gauge block serving as the standard deform, permanent errors can be caused for checking other measuring tools.
