Switching output is relay output, can achieve the remote-control and alarm output. The switch input adapts the method of on-off signal input and powered by outer power supply. It can be gotten by meter when there is a change of on or off via a switching input module. The parameter of switching input can not only get and show the state of local switching information but also achieve the communication via RS485, which called “remote information” function.

Function Description

Measurement

The meter can measure all electrical parameters such as voltage, current, active power, reactive power, apparent power, power factor, frequency, 31st harmonic and total harmonic. The value format of voltage, current, frequency and power are listed as below.
Example: U = 220.1V，f = 49.98Hz, I = 1.99A，P = 0.439kW

Calculating

The meter can calculate the current active energy, forward active energy, reversing active energy, forward reactive energy and reversing reactive energy.

Timing

The meter has 2 time lists, and can be divided into 4 time zones per year. Each time list can be divided into 8 time periods and 4 tariff (F1、 F2、F3、F4). The main purpose of multi-tariff is promote the energy efficiency and economic benefits.

Demand

There are some definitions on demand:

Demand	The average power in the demand cycle.
Maximum demand	The maximum value of demand in a period of time.
Demand cycle	The time period between two same average value of demand.

The default demand cycle is 15 minutes, slip time is 1 minute. The meter can measure 4 kinds of maximum demand: forward active, reversing active, inductance performance reactive, capacitance performance reactive maximum demand and the occur time.

History data statistics

The meter can record last 48 months or last 90 days history energy in each tariff.

Switching input and output

The switch input adapts the method of on-off signal input and powered by outer power supply. It can be gotten by meter when there is a change of on or off via a switching input module. The parameter of switching input can not only get and show the state of local switching information but also achieve the communication via RS485, which called “remote information” function.

Temperature measurement

The meter support three path of outlay NTC temperature measurement, the range of temperature is -40℃~99℃.

There will not be power or power factor on each phase and will only show total power and power factor (Active, reactive, apparent) under the three phase three lines.
There will not be date, time, maximum demand and energy by time without the function of multi-tariff rate.

Current forward active energy 12.34kWh
Current reversing active energy 12.34kWh
Current forward reactive energy 12.34kWh
Current forward active energy 12.34kWh
Current power is 1.234kW

Note: There are parts of the display function, and other menus are familiar with the example above. The customers can understand the meaning refer to the above examples.

Key menu

Press at any main menu and get in “PASS” interface, and then press show “0000”, and enter the code. If you enter a wrong code, it will show “fail” and back to main menu; and if you enter a right code, you can set the parameter. After setting the parameter and press , it will show “save” and save the change by pressing in “yes” interface and quit without save by pressing in “no” interface.
