3. THE PRINCIPLE FUNCTIONS
3.1. It has measure forward and reverse active energy 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. It can measure,store and display the voltage, current, power, power factor, frequency and other operating parameters and status 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. It has freezing functions such as instantaneous freezing, regular freezing, daily freezing, agreed freezing and hour freezing.
3.5. It has the function of event recording such as zero clearing, programming, proofread, power down, pulling and closing the brake, etc.
3.6. 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.
3.7. Active 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).
3.8. After the meter is powered on and the LoRaWAN module is connected to the network, the meter is automatically calibrated.

4.2. Electricity meter is displayed by LCD
The specific display items are listed as follows:
| No. | LCD figure | explain |
| 1 | | Character that can indicate that: Current, previous month, the previous twelve months cumulative total electricity consumption and electricity consumption at various rates. |
| 2 | | Data display and the corresponding unit symbol |
| 3 | | 1) In communication 2) Reverse power indication 3) ① ② represents periods sets 1 and 2 4) Undervoltage indication of the battery or supercapacitor voltage 5) Allow the programming status indication 6) Three times of password verification error indication |
| 4 | T1 T2 T3 T4 | Indicates current rate status (peak valley) |
| 5 | ----ON ----OFF | ----ON is relay state on ----OFF is relay state off |
4.3. Status indicator lamp
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.
LoRaWAN/NB-I o T/C at.1 Module status indicator: green. Always on indicates online, and flashing indicates going online.

5.2. Wiring diagram
Of these, 5,6 are reactive pulse output. 7,8 are active pulse output. 9,10 are multifunctional clock output. And 11,12 are RS485 output.
5.3. Installation
Live installation of wiring is strictly prohibited!
The electricity meter shall be installed indoors as far as possible. Special instrument box protection shall be used for outdoor installation. The installation bottom plate shall be fixed on the wall with strong fire resistance and not easy to vibration. There must be no corrosive gases in the surrounding air where the meter is installed. Avoid dust, salt spray, etc.
When using the electricity meter, the wiring must be conducted strictly according to the wiring diagram in the tail cover of the meter. It is recommended to use copper wire for the lead connected to the terminal seat. The screws of the fixed lead in the terminal seat should be tightened to avoid burning the electricity meter due to bad contact and heating.
Ammeters must be transported and stored under the original packaging conditions. Products shall not be severely impacted during transportation and unpacking, and shall be transported and stored according to GB / T 25480-2010 Basic Environmental Conditions for Instrument Transportation and Storage and Test Methods as stipulated in 2010. The products should be stored in the warehouse and placed on the platform frame. The stacking height shall not exceed five layers. No corrosive gases shall be present in the stored environment.
7. WARRANTY PERIOD AND AFTER-SALES SERVICE
