Features:This is a electric monitoring test multimeter which can be used to test power, energy, voltage and current then displayed on a PC or other terminals. It can store data when power off, and store the accumulated energy data before power off. Designed with one key reset button, you can reset energy data by simply pressing one button. The TTL serial port can communicate, read and set parameters with a variety of terminals through a USB adapter.This is a electric monitoring test multimeter which can be used to test power, energy, voltage and current.The connection of this module is divided into 2 parts: voltage, current input connection and serial port communication, and you can use different TTL adapters to make it communicate with various terminals.Comes with a random color current transformer and a USB adapter for convenient use so you do not have to buy separately.There is a button for energy data reset, simply press and hold the button for 5 seconds until display flashes and release, then press the button again to finish energy reset.It has four digital displays and can also displays through PC or other terminals. You can download the software for PC. For other terminals, it need to be programmed by yourself. 1. Voltage(V), current(A), average power(kW), energy(kWh) measurement.2. Energy reset by pressing one button.3. Store data when power off(store the accumulated energy data before power off).4. LCD display function(display voltage, current, average power, energy).5. Serial port communication function(TTL serial port can communicate, read and set parameters with a variety of terminals through a USB adapter).6. Overload alarm.7.

If it need to communicate with a device which has USB or RS232 (such as computer), a TTL adapter is required. In the below table are the communication protocols of this module:
Function  Head  Data1- Data5  Sum 
Voltage  B0  C0 A8 01 01 00 (Computer sends a command to read the voltage value)  1A 
A0  00 E6 02 00 00 (Meter reply the voltage value is 230.2V)  88 
Current  B1  C0 A8 01 01 00 (Computer sends a command to read the current value)  1B 
A1  00 11 20 00 00 (Meter reply the current value is 17.32A)  D2 
Average Power  B2  C0 A8 01 01 00 (Computer sends a command to read the average power value)  1C 
A2  08 98 00 00 00 (Meter reply the average power value is 2200w)  42 
Read Energy  B3  C0 A8 01 01 00 (Computer sends a command to read the energy value)  1D 
A3  01 86 9f 00 00 (Meter reply the energy value is 99999wh)  C9 
Set Module Address  B4  C0 A8 01 01 00 (Computer sends a command to set the address, the address is 192.168.1.1)  1E 
A4  00 00 00 00 00 (Meter reply the address was successfully set)  A4 
Set Power Alarm Threshold  B5  C0 A8 01 01 14 (computer sends a command to set a power alarm threshold)  33 
A5  00 00 00 00 00 (Meter reply the power alarm threshold  was successfully set)  A5 
Illustration of Communication Protocol: 1. Set the communication address: 192.168.1.1Send Command: B4 C0 A8 01 01 00 1EReply Data: A4 00 00 00 00 00 A4 Note: The above example illustrate that setting the communication address as 192.168.1.1 (the user can set their own address based on their preferences and needs), sending command and automatic replying data are as shown above, the data are expressed in hexadecimal; the last byte of the sending and replying data are 1E and A4, which is cumulative sum. In sending commands: B4 + C0 + A8 + 01 + 01 + 00 = 21E (hexadecimal), the cumulative sum data is 21E, take the last two bytes 1E as the cumulative sum data in sending commands; in reply data: A4 + 00 + 00 + 00 + 00 + 00 = A4 (hexadecimal), the cumulative sum data is A4, which is the cumulative sum data in reply. 2. Set the power alarm threshold: 20 KWSend command: B5 C0 A8 01 01 14 33Reply data: A5 00 00 00 00 00 A5 Note: 14 in the sending command is the alarm threshold value (14 is a hexadecimal data representation, which converted to decimal is 20). The power alarm value of this module is based on KW units, and the minimum alarm value is 1KW, the maximum value is 22KW. 3. Read the voltageSend command: B0 C0 A8 01 01 00 1AReply data: A0 00 E6 02 00 00 88 Note: Reply voltage data is D1D2D3 = 00 E6 02, 00 E6 represent the integer-bit of the voltage, 02 represent the decimal of the voltage, the decimal is one digit, converts 00 E6 to decimal is 230; converts 02 to decimal is 2, so the current voltage value is 230.2V. 4. Read the currentSend command: B1 C0 A8 01 01 00 1BReply data: A1 00 11 20 00 00 D2 Note: Reply current data is D2D3 = 11 20, 11 represent the integer-bit of the current, 20 represent the decimal of the current, the current decimal is two digits, converts 11 to decimal is 17; converts 20 to decimal is 32, so the current value is 17.32 A. 5. Read the powerSend command: B2 C0 A8 01 01 00 1CReply data: A2 08 98 00 00 00 42 Note: Reply power data is D1D2 = 08 98, converts 08 98 to decimal is 2200, so the current voltage value is 2200W. 6. Read the energySend command: B3 C0 A8 01 01 00 1DReply data: A3 01 86 9F 00 00 C9 Note: Reply energy data is D1D2D3 = 01 86 9F, converts 01 86 9F to decimal is 99999, so the accumulated energy is 99999Wh. Illustration of Communication 1. Connect hardware according to the wiring diagram below. 2.
