metering
Measure positive/negative active energy and have automatic identification and indication of power direction.
The total, peak, peak, flat, and valley electrical energy are stored separately and stored in corresponding storage units.
The electricity meter can store data for 3 months, and the default date for freezing and transferring electricity is 24:00 at the end of the month (frozen at the end of the month).
After a power outage, all stored data is not lost and can be maintained for more than 10 years.
output
Active electrical energy pulse output, used for meter calibration and energy collection.
Clock and time slot rates
Internal hardware clock, clock error within 0.5s/day.
Programmable settings for peak, peak, flat, and valley rates, with 8 daily intervals and a minimum interval of 1 hour.
programming
Programming settings are carried out through the upper computer.
Time and date settings.
Setting the address of the electricity meter.
Rate period settings.
Setting the battery level to zero.
display
7-bit wide temperature LCD display.
Real time data rotation display, with a cyclic display time of 4 seconds.
The electrical energy pulse is indicated by a red LED.
Four types of tariff periods are indicated in Chinese characters: sharp, peak, flat, and valley.

Installation diagram
The three-phase multifunctional power instrument adopts a 35mm standard guide rail installation method, as shown in the following figure:
Wiring method
This series of three-phase multifunctional power instruments supports two connection methods: direct connection and CT connection through current transformers.
Note: Please refer to the actual wiring diagram of the instrument during actual wiring, where variable 6 in the wiring diagram of 4P-1 represents the selectivity of reactive and clock pulses.
