In order to ensure the reliability of the measurement results of the gauge, there is one work that the user must do before use, that is, to check the gauge correctly and carefully.

    First, we must check the drawings to see if the gauge is consistent with the required inspection size and tolerance, so as to avoid errors and cause a large number of waste products.
    2. Check whether the gauge has qualified marks or other certificates.
    Third, check whether there are rust spots, scratches and burrs and other defects on the working surface of the gauge, because these defects are easy to cause the surface quality of the inspected workpiece to decline, especially non-ferrous metal workpiece with higher tolerance level and surface roughness.
    Fourth, check whether the gauge head and the handle are firmly and reliably connected.
    Fifth, check the parts of the workpiece to be inspected, especially the inner hole, whether there are burrs, bumps, scratches and other defects.
