3.1. 3.1 Metering positive and negative active power, positive and negative direction active power, 1-4 quadrant reactive power, and ABC phase separation active power and reactive power functions. Electrical energy should be accumulated and stored separately for electric energy and total electrical energy at each time period such as tips, peaks, flats, and valleys. And it can also store and display the power of the previous 12 months.
3.2. 3.2 It can measure, store and display the operating parameters and states of ABC such as each phase voltage, current, total and three-phase active reactive power, three-phase active reactive power, total and three-phase power factor and frequency of the current electricity meter. And it has overload protection function.
3.3 There are two sets of rates (sharp, peak, flat, valley) and periods that can be programmed arbitrarily, and another set of rates and periods can be start to used at the set time point. Each set of rate time periods can be set with at least 2 time zones for a year. At least 14 time periods can be set within 24 hours. The minimum time period interval is 15 minutes. The time period can be set across zero points.
3.4 Record the maximum demand and occurrence time of forward active, reverse active, positive reactive and reverse active power in that month.
3.5It has freezing functions such as instantaneous freezing, regular freezing, daily freezing, agreed freezing and hour freezing.
3.6 It has the function of event recording such as zero clearing, programming, proofread, power down, pulling and closing the brake, etc.
3.7 Remote disconnection and power transmission function. Power off command is issued through communication interface such as RS485 to cut off the user's load loop; Or issue a power transmission instruction to turn on the user load loop.
3.8Active upload / bidirectional transparent transmission function. Actively upload the data to the corresponding platform through the LoRaWAN wireless network, with a default interval of 4 hours (settable).
3.9 After the meter is powered on and the LoRaWAN module is connected to the network, the meter is automatically calibrated.

l Overdraw indication: overdraft electricity when "surplus" seconds flash, overdraft power off power when "surplus"speeds flash.
l Out- of-phase indication: When ABC is out of phase, the corresponding character of ABC in the lower row flashes seconds.
l Smart Secure Three Phase Energy Meter IoT 4G Wifi Wireless Energy Monitoring System 7Wrong phase indication: this indicator seconds flashes when ABC three-phase voltage is wrong phase; this indicator speeds flashes when ABC three-phase current is wrong. This indicator does not appear when there are missing phases.
 
The electricity meter uses a bright, long-life LED as a pulse indicator light.
It has active power pulse indicator light: red, usually go out, flashing when measuring active power.
It has reactive power pulse indicator light: red, usually go out, flashing when measuring active power.
Trip indicator light: yellow. Often out indicates the relay closed state.Often bright indicates the relay off state.
LoRaWAN module status indicator: green. Often bright indicates that is online, flashing is going online.
