Through the measurement of selected electrical energy check standard,Using the maximum permissible errors and calibration certificate given calibration results and its uncertainty of the standard which to be check, to determine the "center line of the check measurement control chart, Using the Excel spreadsheet to draw the control limit, Make each check measurements in figure intuitive accurately reflect the error or the value change of direction and size of the standard which to be check,The results can also be used as the basis for assessment of stability for measurement standard.
