Outlay NTC temperature measurement
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 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
- Current forward active demand is 1.234kW
- Voltage on A phase is 123.4V
- Current on A phase is 12.34A
- Voltage on A phase is 123.4V
- Temperature on T2 is 25.5 cent degree
- Voltage on A phase is Temperature on T3 is 25.5 cent degree123.4V
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.
