Connect the live (L) and neutral (N) wires according to the diagram below. The input (Entry end) and output (Outline) terminals are clearly marked on the device.
Important Safety Note: Electrical installation should only be performed by qualified personnel. Always ensure the main power supply is turned off before connecting or disconnecting any wires.
5. Operating Instructions
5.1 Initial Power-Up and Display
Once correctly wired and powered on, the LCD HD display will illuminate, showing the 6 measurement parameters. The display offers a wide viewing angle (178°) for clear data visibility.
5.2 WiFi Connection and App Control
- Download the Tuya Smart or Smart Life application from your mobile device's app store.
- Register or log in to your account.
- Follow the in-app instructions to add a new device. Ensure your mobile device is connected to a 2.4GHz WiFi network.
- Once connected, you can monitor real-time voltage, current, power, and energy consumption directly from your smartphone.
- The app also allows for remote control and scheduling of connected devices, if applicable to your setup.
5.3 Energy Data Reset
To reset the accumulated electrical energy (KWh) data, locate the reset button on the device (often labeled 'M' or 'Reset'). Press and hold this button for a few seconds until the KWh reading resets to zero. This allows you to track energy consumption for specific periods or tests.
6. Maintenance
6.1 General Care
Keep the meter clean and free from dust. Use a soft, dry cloth for cleaning. Avoid using abrasive cleaners or solvents, which may damage the display or casing. Ensure the device is installed in a well-ventilated area and within its specified operating temperature range.
6.2 Data Storage
The meter features an automatic power-off memory function. This means that in the event of a power outage, the last recorded energy data is saved. When power is restored, the meter continues to accumulate data from the last saved point, ensuring continuous monitoring without loss of historical data.
7. Troubleshooting
- No Display: Check the power supply and wiring connections. Ensure the voltage is within the specified AC 85-265V range.
- Incorrect Readings: Verify that the wiring is correct according to the diagram. Ensure the load is connected properly.
- WiFi Connection Issues: Ensure your router is operating on a 2.4GHz frequency. Check that the meter is within range of your WiFi network. Restart your router and the meter, then attempt to reconnect via the Tuya Smart app.
- App Not Showing Data: Confirm the meter is successfully connected to the app. Check your internet connection. Update the app to the latest version.
