Electronic single-phase energy meter is a common power metering device in modern households. However, sometimes we encounter the problem of black screens on electronic single-phase energy meters. This article will provide you with a solution to help you better understand this issue.

Reason for the problem

The black screen issue of electronic single-phase energy meters may be due to the built-in lithium battery running out of power or being damaged, or it may be due to a damaged LCD screen or circuit malfunction.

Problem observation

Observe whether the pulse light on the electricity meter is flashing and how fast it is flashing. If there are no high-power appliances in use and the pulse light flashes rapidly, it may be a circuit fault and you need to contact the power supply bureau to replace the meter as soon as possible. If the pulse light flashes slowly, there is also a problem, which may cause the actual electricity consumption to be inconsistent with the measurement.

Solution

It is recommended to communicate with the power department for repair as soon as possible in order to promptly resolve this issue.
