Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or not turning on. | No power from the outlet; internal battery depleted. | Ensure the meter is securely plugged into a live power outlet. Allow several hours for the internal battery to charge. |
| "OVERLOAD" flashes on the screen. | Connected appliance exceeds the maximum load (3680W). | Immediately unplug the appliance. Do not connect appliances with power consumption exceeding 3680W. |
| Incorrect cost calculation. | Electricity price (COST/KWh) is set incorrectly. | Refer to the "Setting Electricity Price" section in Setup and adjust the value according to your local electricity rates. |
| Data lost after power outage. | Internal backup battery is not sufficiently charged or has reached end of life. | Ensure the meter is plugged in for at least 5-10 hours initially to fully charge the backup battery. If the issue persists, contact customer support. |
