- Mode 1: Time/Watt/Money Cost - Displays current time, real-time power consumption (Watts), and accumulated cost.
- Mode 2: Days/Cumulative Energy Consumption (kWh) - Shows the number of days the device has been monitoring and the total accumulated kilowatt-hours.
- Mode 3: Voltage/Frequency - Displays the current voltage (V) and frequency (Hz) of the power supply.
- Mode 4: Current/Power Factor - Shows the current (A) and power factor.
- Mode 5: Minimum Power Recording - Displays the lowest power consumption recorded.
- Mode 6: Maximum Power Recording - Displays the highest power consumption recorded.
- Mode 7: Cost per kWh Setting - Allows adjustment of the electricity unit price (as described in Setup).
5.2 Real-time Monitoring
Once connected, the meter automatically begins monitoring and recording the electricity consumption and costs of the connected device. This helps you understand the energy footprint of your appliances.

5.4 Overload Warning
If the connected device's current load exceeds 3680W, the LCD screen will flash "OVERLOAD" to alert you. This feature protects both the connected device and the meter from potential damage.

5.5 Data Memory Function
The built-in backup battery ensures that the meter retains all recorded data even during a power outage.

5.6 Resetting Data
To clear all settings and recorded data, press the "RESET" button. This is useful for starting new monitoring periods or for initial setup.
6. Important Notes on Operation
- The unit price for cost calculation must be entered in Euros.
- The displayed time is the running time and only counts when the appliance is actively consuming power. For intermittent appliances (e.g., freezers), this reflects actual operational time.
- The device only records data if the working power of the appliance is greater than 2W. Appliances in standby mode with less than 2W consumption will not be recorded.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank. | No power supply; device not plugged in correctly. | Ensure the meter is securely plugged into a live wall socket. Check the wall socket with another appliance. |
| "OVERLOAD" warning flashes. | Connected appliance exceeds 3680W. | Unplug the appliance immediately. Do not connect appliances with power consumption above 3680W. |
| Data not recording. | Appliance power consumption is below 2W. | The meter only records consumption above 2W. This is normal for very low-power or standby devices. |
| Incorrect cost calculation. | Incorrect unit price set. | Refer to Section 4.4 "Setting Unit Cost" to re-enter the correct electricity price per kWh. Ensure it's in Euros. |
