7.Communication method: RS485, infrared
8.Display information: cumulative electricity consumption in the current month and last month, cumulative electric energy indication value and total accumulated electric energy indication value, current date and time, alarm code or prompt, communication status prompt, meter number of electric energy meter, etc.
9.Optional function- switch built-in
Optional direct access type or transformer access type, optional function- switch built-in
switch built-in: miniature circuit breaker switch is installed inside the meter, and the meter is integrated, advantages: simple structure and cheap price
10.Optional function-switch external
Optional direct access type or transformer access type, optional function- switch external
switch external: miniature circuit breaker is set separately, the electric meter controls the opening / closing of the external circuit breaker through the control terminal
advantages: external circuit breaker ,strong current interruption , not easy to damage.
11.Security Anti-theft
Software: add special encryption algorithm; open the alarm record.
Hardware: Add the top cover and the tamper-evident seal of the tail cover.
