Scope of application

1, the measurement function: measuring positive and negative active, capacitive reactive power and round quadrant reactive energy;

2, time-measurement: with four rates, 12 time zones, divided into 10 days a day, a total of 4 sets of day time to choose from;

3, the monthly statistics of electricity: a total power and time sharing power and the total function of the previous day and last month's total electricity consumption measurement function;

4, the maximum demand: record the maximum demand and its emergence time, demand cycle default is 15 minutes, slip time default is 1 minute;

5, clock, calendar function (summer time 10 years automatic conversion)

6, power failure display (optional)

7, time recording function: record the occurrence time of a variety of events and the current state, such as phase failure, power failure, programming, reset, battery usage,

8, communication function: can use RS485 communication interface or infrared port, and handheld computers, computers or infrared remote control to communicate.
