Q&A
Q1: What is the smart energy meter? What are the functions of smart energy meter?
A1: 1) As a new-type energy meter, smart energy meter adopts digital metering technology, supports various actual requirements, such as bidirectional metering, step tariff, TOU tariff, peak-valley tariff, etc. It’s also the technology base to achieve distributed power measurement, two-way interactive service, smart home and intelligent community.
2) Smart energy meter also consists of measuring unit, data processing unit, communication unit, etc., and has various functions such as energy metering, data processing, real time monitoring, automatic control, information exchange, etc.
Q2: What kind of error message code prompts do LCD screen of smart energy meter have?
A2: When malfunction appears in energy meter, it will display error message codes:
Q: (1) Err-01 Control loop error
(2) Err-02 ESAM error
(3) Err-04 Low battery voltage of clock
(4) Err-08 Clock failure
(5) Err-10 Authentication error
(6) Err-16 Change key error
