How to check the remaining power of a prepaid energy meter?

Checking the remaining power of a prepaid energy meter is actually very intuitive, mainly through the following methods:

1. Directly observe the LCD display screen

The vast majority of prepaid energy meters are equipped with LCD displays, which will cyclically display key information, including total electricity consumption, remaining electricity, and recharged electricity. The smallest value is usually the remaining battery level, with the last digit being the decimal place. For example, displaying "866" means the remaining battery level is 86.6 degrees. Some electric meters will be marked with the letter "L" before the remaining power, or directly display the words "remaining power".

2. Button switching query

Some electric meters are equipped with function buttons (such as "query" and "balance" buttons), which can be switched between displaying content by short or long pressing. The general operating logic is:

Short press: Cycle to switch between total power, remaining power, and recharged power

Long press: Enter the advanced menu (refer to the instruction manual)

It is recommended to carefully read the meter manual before operation, as there may be slight differences in button logic among different brands.

3. Remote inquiry through mobile app

The new generation of intelligent prepaid energy meters supports remote management. Users can bind their account number through the official app or designated mini program of the power company to view the remaining electricity, electricity usage records, and electricity bill balance in real time. Some platforms also provide functions such as low battery warning and online recharge.

4. Card insertion query (applicable to IC card table)

Insert the power purchase card into the slot of the meter card, and the display screen will automatically show the current remaining power. If the electricity meter does not display, you can try cleaning the gold finger on the card and retry.

precautions

Ensure that the electricity meter is powered on before operation

Avoid touching the electricity meter with wet hands

In case of abnormal display (such as garbled characters or sudden numerical changes), contact the power supply department for maintenance in a timely manner

When the remaining battery level is below the alarm threshold, it is recommended to recharge in a timely manner to avoid power outages

By mastering these query methods, one can easily manage electricity consumption and have a clear understanding.
