6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or not turning on. | No power to the outlet; device malfunction. | Check if the wall outlet is working. Try plugging another device into the outlet. If the problem persists, the wattmeter may be faulty. |
| Readings seem inaccurate. | Incorrect electricity cost setting; device malfunction. | Verify your electricity cost setting (Section 5.2). Perform a full reset (Section 5.8). If still inaccurate, compare with another known measurement device. |
| Overload alarm triggers frequently. | Connected appliance exceeds set overload limit; overload limit set too low. | Check the power consumption of your appliance. Adjust the overload alarm limit if necessary (Section 5.3), ensuring it does not exceed the device's maximum capacity (3680W). |
| Backlight not working or staying on. | Backlight duration setting; device malfunction. | Check and adjust the backlight duration setting (Section 5.9). |
| Data is lost after unplugging. | Internal battery issue (for data retention); device malfunction. | The device has an internal battery (CR2032) for data retention. If data is consistently lost, the battery may need replacement or there is a device fault. |
