The correct use of measuring tools and measuring instruments is an important condition for maintaining its accuracy and extending its service life, which is a common sense that every tester must know.
    1The use of the instrument must be in accordance with the operating rules and regulations, not for the sake of saving trouble and illegal operation.
    2The management and use of measuring tools and measuring instruments must be implemented to people, and the maintenance system must be developed and carefully implemented. In addition to the specified use of the instrument, other people must obtain the consent of the person in charge and the user if they want to use it.
    3When the moving part of the instrument fails, it cannot be forced to rotate or move before the cause is identified, so as to avoid man-made damage.
    4When measuring parts on the machine tool, it is necessary to wait for the parts to be completely stopped, otherwise it will not only cause the measuring surface of the measuring tool to lose accuracy due to premature wear, but also cause accidents. Especially when turning workers use external calipers, do not think that the caliper is simple, grinding a little does not matter. It should be noted that there are often porosity and shrinkage holes in the casting, once the foot falls into the porosity, it may pull the operator's hand into it, causing a serious accident.

    5Before measuring, the measuring surface of the measuring tool and the measured surface of the part should be wiped clean, so as not to affect the measurement accuracy due to the existence of dirt. It is wrong to use precision measuring tools such as vernier calipers, dial gauges and dial gauges to measure the forging blank or the surface with abrasive agents (such as emery, etc.), which is easy to make the measuring surface wear quickly and lose accuracy.
