The invention provides a method for calibrating a meter electric energy meter, which comprises the following steps: the first step is to install the electric energy meter of the meter; the second step is to obtain the photoelectric sampling accuracy of the meter calibration chip; the third step is to determine the gain of 1.0 Whether it is qualified, if it is not qualified, then enter the fourth step, if it is qualified, then enter the fifth step; the fourth step, the calibration chip finds out the abnormal voltage point x, abnormal current point y, and manually adjusts x and y; The fifth step is to judge whether the 0.5L angle difference is qualified. If it is not qualified, it will enter the sixth step. If it is qualified, it will enter the seventh step. ; The seventh step is to judge whether the small current bias is qualified, if it is not qualified, then enter the eighth step, if it is qualified, then enter the ninth step; the eighth step, the calibration chip finds out the abnormal bias point n, manually n debugging; the ninth step, the calibration is completed. The invention has fewer meter calibration steps, greatly reduces the difficulty of meter calibration and improves the meter calibration efficiency.
