Operating Instructions
Once an appliance is connected and powered on, the meter will begin measuring its electricity consumption. Use the buttons to navigate through different display modes and settings.
Button Functions:
- HISTORY: Press to view historical data or switch between different time-based measurements (e.g., daily, weekly, total).
- ENERGY/+: Cycles through various energy-related displays such as current power (W), voltage (V), amperage (A), and total energy consumption (kWh). Also used to increase values during setting.
- COST/-: Displays the calculated cost of electricity consumed. Can also be used to decrease values during setting.
- SET/OK: Enters setting mode (e.g., to set electricity tariff) or confirms a selection.
- RESET: Resets all accumulated data and settings to default. Use with caution.
To set the electricity tariff for cost calculation, press the SET/OK button and use ENERGY/+ and COST/- to adjust the price per kWh, then press SET/OK again to confirm.
Maintenance
- Clean the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Ensure the ventilation slots (if any) are not blocked.
- Replace the backup batteries (LR44/AG13) periodically, or if the display shows signs of fading when unplugged.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank. | No power from wall socket or backup batteries are depleted. | Check wall socket. Replace LR44/AG13 backup batteries. |
| No readings for connected appliance. | Appliance not powered on, or not drawing sufficient power (below 2W). | Ensure appliance is switched on. The meter has a minimum measurement threshold of 2W. |
| Overload indicator (LED) is on. | Connected appliance exceeds the maximum load of 3680 W. | Unplug the appliance immediately. Do not connect appliances exceeding 3680 W. |
| Incorrect cost calculation. | Electricity tariff not set correctly. | Enter setting mode (SET/OK) and adjust the price per kWh to your local tariff. |
