B. self check is carried out in passage self check, a plurality of passages automatically simultaneously;
C. get into calibration mode, managing electric quantity IC is carried out the burning of electric current and voltage calibration and product inner parameter;
D. calibration result is judged, each passage is calibrated burning result's judgement, and calibration data records is saved to local storage and or server;
E. get into checking mode, from local storage with or server obtain each calibrate data, directly get into checking mode, indicate the channel errors code, showing needs the verification passage; If have mistake then shield this passage;
F. the result of output verification, and be stored in local storage with or server in;
More than each step all in same equipment, carry out.
Wherein, described calibration mode step is following:
C1. on-load voltage;
C2. loading current;
C3. burning information is carried out synchronization check in the time of burning;
