- Display Brightness: Adjust the screen brightness.
- Standby Brightness: Set brightness for standby mode.
- Over-Voltage Threshold: Set the maximum allowed voltage.
- Over-Current Threshold: Set the maximum allowed current.
- Over-Power Threshold: Set the maximum allowed power.
- Price: Set the unit price for electricity calculation.
- Default Settings: Restore factory default settings.
- Reset: Clear accumulated data.
Maintenance
1. Cleaning
To maintain optimal performance and readability, gently wipe the screen and casing with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the display or finish.
2. Protective Film
The meter's screen comes with a protective film. It is recommended to keep this film on during installation to prevent scratches. Once installed, you may carefully remove it for clearer viewing.
Troubleshooting
1. No Display / Incorrect Readings
- Ensure the meter is correctly wired and receiving power (AC50-300V).
- Verify the current transformer (CT) is correctly installed around the live wire of the load.
- Check for loose connections.
2. Bluetooth Connection Issues
- Ensure Bluetooth is enabled on your mobile device.
- Verify the AT24 Voltmeter is powered on and its Bluetooth indicator is flashing.
- Check APP permissions for Bluetooth and location access (refer to Figure 6 for Android permission settings).
- Restart the APP and try reconnecting.
- Ensure the APP is the latest version.
3. Over-Voltage/Current/Power Alarms
If the meter displays an OVT (Over-Voltage), OCT (Over-Current), or OPT (Over-Power) alarm, it indicates that the measured value has exceeded the set threshold. Check your electrical load and adjust the thresholds in the background settings if necessary (refer to Figure 8).
