Multi-user meter manufacturers will give you detailed methods to check the correct changes of prepaid meters:
The composition and working principle of prepaid meters are very different from traditional inductive energy meters. Inductive meters are mainly composed of aluminum discs, current and voltage coils, permanent magnets and other components, and their working principle is mainly through the current coil and the The eddy current interaction induced in the moving lead pan is measured. The electronic prepayment meter is mainly composed of electronic components, and its working principle is to first sample the user's power supply voltage and current in real time, and then use a dedicated electric energy meter to integrate The circuit processes the sampled voltage and current signals and converts them into pulse output that is proportional to the electrical energy. After that, it is processed and controlled by a single-chip microcomputer, and the pulses are displayed as power consumption and output.
Open the meter box of the prepaid meter, "cut off the ** wire on the left side of the meter, and leave the meter in a complete power-off state for 30 seconds to clear the meter's memory data", and then re-connect this wire, the meter will display "Total usage Power, remaining power, meter number, capacity limitation method, capacity limitation "and other data.
Multi-user electricity meter manufacturers can use this method to check whether the data is correctly written into the electricity meter. If you want to know more related questions then call and we will contact you within ** time to let you know more
