Main functions and features of electric energy meter:

Metering function

1) It has the functions of forward active energy and reverse active energy measurement, can store its data, and can set the combined active power according to this. Factory default: Combined active energy = forward active energy + reverse active energy.

2) With the function of time-sharing measurement, active electric energy is accumulated and stored in total, sharp, peak, flat and valley electric energy according to the corresponding period.

3) At least store the total electric energy of the last 12 months and the electric energy of each rate; the data storage demarcation time is at the beginning of the month or at the hour of the 1st to 28th of each month.

4) It has the function of freezing electricity (conventional freezing: freezing at a fixed time every month, and saving frozen data once a month).

5) Active energy cannot be cleared.

It can measure and display the current operating parameters such as voltage, live current, power and power factor of the current energy meter.

record

1) Record the total number of times the watch cover is opened, and the occurrence and end time of the last 10 watch cover opening events.

2) Record the total number of programming, the time of the last 10 programming, the operator code, and the data identification of the programming item.

3) Record the total number of time corrections (excluding broadcast time correction), the time of the last 10 time corrections, and the operator code.

4) Record the total number of power outages and accumulated power outage time, and the time when the last 10 power outages occurred and ended.

485 communication, its communication protocol is completely in accordance with DL / T645-2007; the default baud rate is 2400bps, and the baud rate can be set.

Infrared communication 38K two-way modulation signal has a communication protocol that fully complies with DL / T645-2007; the default baud rate is 1200bps.

The LCD display with backlight is clear and intuitive, with the functions of circular display, key display and power failure display;

Two levels of protection are implemented for programming events: password authority plus hardware protection.
