百分表检定仪是进行指示量具校准用的主标准器 ,其示值误差是否超差 ,将直接影响到指示量具出具校准数据的准确性和可靠性 ,所以必须要对百分表检定仪的示值误差进行定期检查。当不具备对百分表检定仪自行进行周期检定的条件时 ,采用扭簧表和三等量块检查百分表检定仪示值误差? Dial indicator is used to indicate the main gauge used to calibrate the gauge, indicating the value of tolerance is out of tolerance, will directly affect the accuracy of the instructions issued by the calibration data and reliability, it must be on the dial indicator Indication of error for periodic inspection. When you do not have the conditions for the cycle checker on your own, use a torsion spring and a third equalizer to check the indication error of the dial indicator.
