Storage limited temperature: -20-+80 celsius
10) Service life: >10 years
11) Battery life: ≥5 years
12) Power pulse width: (80±10) ms
Main functions:
1) Accurately measure the forward and reverse active energy, total active energy, forward and reverse reactive energy, total reactive energy (can be optional of inductive and capacitive reactive energy)
2) Pre-define 12 time zone, 16 time sections, 4 tariffs, 8 day programs, 32 holiday, and the workday can be pre-defined specially from Saturday, Sunday
3) Display metering data, currently power status, currently meter working status and preset parameter and other information
4) When losing one or two phase voltage, the relevant symbol will disappear on the LCD
5) When it has low power of battery, relevant symbols will display on the LCD
6) Self-diagnosed function: can auto detect the non-volatile memory error, clock error and indicate accordingly
7) Communication interface: infrared communication interface (the RS485 interface is optional)
8) Power failure display: when power failure, the LCD can be waken up by pressing the relevant button. 15 seconds later after stopping pressing, the meter will auto enter dormancy status
9) Auto summer/ winter time shift
