description The invention relates to a low-voltage electricity larceny analyzer and a use method, and belongs to the technical field of power supply. According to the technical scheme, a real-time clock circuit (2), a power supply circuit (3), a FLASH memory circuit (4), a Bluetooth module circuit (7) and a 4G communication module circuit (8) are respectively connected with an embedded microcontroller (1), and the embedded microcontroller is connected with a concentrator through an RS-232 interface circuit (5) and an RS-485 interface circuit (6). The analyzer has four main functions of checking the cover opening record of the electric energy meter, checking the current loss of the electric energy meter, checking the incoming and outgoing line current abnormity of the electric energy meter and checking the clock out-of-tolerance, data abnormity is judged by adopting a method for calculating the standard deviation through Bessel and Pearl algorithms, and compared with household-by-household checking, the daily workload of
