Digital Meter Watt Power Volt Amp TTL Current Test Module PZEM-004 T With Coil 0-100A 80-260V ACV Electronic Kit
Feature :
1. Electrical parameter measurement function (voltage, current, active power).
2. Power button clear function.
3. Power-off data storage function (accumulated power savings before shutdown).
4. PC display function (displays voltage, current, and active power).
5. Serial communication function (built-in TTL serial interface, communicates with the adapter board via various terminals to read and set parameters).
B. Front Display and Keys
UI:
The PC display window consists of four windows for displaying voltage, current, power, and wattage parameters, as shown in the figure.
Display Format:
1. Power: Measuring range 0 to 22kW
The display format is 0 to 0.000 to 9.999 within 10 kW;
The display format is 10.00 to 22.00 within 10 to 22 kW.
Power: Measurement range 0 to 9999 kWh:
Display format within 10 kWh: 0 to 0.000 to 9.999;
Display format within 10 kWh: 10.00 to 99.99;
Display format within 10 to 100 kWh: 100.0 to 999.9;
Display format within 100 to 1000 kWh: 1000 to 9999 kWh;
Display format within 1000 to 9999 kWh: 1000 to 9999 kWh.
Voltage: Measurement range 80 to 260 VAC:
Display format 110.0 to 220.0.
Current: Measurement range 0 to 100 A:
Display format 00.00 to 99.99.
Buttons:
The built-in buttons on the panel are used for power clearing, as shown in Figure 2.
To clear power: Press the ZERO button for 5 seconds and then release it. Press the CLEAR button again to clear the data and exit the power clearing process.
Serial Communication:
The module features a TTL serial data communication interface through the serial port, which can be used to read and set relevant parameters. However, if you to communicate with a device using USB or RS232 (e.g., a computer), you will need a different TTL adapter hardware board (a TTL-to-USB adapter board is required for USB communication; an RS232 adapter board is required for TTL-to-RS232 communication). Detailed connection information for the adapter board can be found in the diagram.
Communication Instructions:
1. Connect the hardware according to the circuit diagram.
2. After connecting the cables, a good first step is to select the supported communication ports COM2, COM3, or COM4 in the PC software. If this is not the case, you will need to modify the port. If you do not see multiple ports, you may need to check.
Notes:
1. This module is intended for indoor use, not outdoor use.
2. The applied load should not exceed the rated power.
3. Ensure correct wiring.
