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
