    1. Operate the die to be calibrated in working condition

    2. If the “GO” gage end (Green) can pass freely, but the NO-GO end (Red) can not pass completely, it means the tool is still qualified

    3. If the “GO” gage end (Green) can not pass, but the NO-GO end (Red) can pass completely, it means the tool is not qualified



    1. After using, the gage should be put into the special tool box to prevent the bending deformation of the gage pin.

    2. Regularly wipe with antirust oil to ensure that the surface of gage pin is clean.
