Pre-paid energy meter precautions and simple troubleshooting
Shandong University of Science and Technology Zhongtian Electronics Co., Ltd. specializes in the production and sales of pre-paid energy meters, DF multi-user smart meters, multi-user energy meters, electronic meters, apartment ** meters, high-current centralized meters, and pre-paid energy meters. .
Pre-paid watt-hour meters are also called quantitative watt-hour meters and IC card watt-hour meters. In addition to the ordinary watt-hour meter's metering function, in particular, users first buy electricity and then use electricity after buying electricity. , It will automatically cut off the power and stop the power supply. The following is an explanation of the pre-paid energy meter by Shandong University of Science and Technology Zhongtian Xiaobian.
1. After the user ’s electricity card ** purchases electricity, it shall be strictly in accordance with one table and one card.
2. The card should be kept properly, and should not be placed with strong magnetic materials, and the surface of the chip of the card should be kept clean.
3. If the purchased power is not used up and there is a power outage, you should first check whether the outlet of the meter has voltage. If there is voltage, you should check other switches and lines. If there is no voltage at the outlet of the meter, you need to check whether it is a brake alarm. For example, when the brake alarm value is set to 10kW • h (settable), when the user ’s power remains to 10kW • h, the meter will lose power. Need to insert the card again to continue power supply.
