Operating Instructions
Understanding Display Modes
The meter cycles through various display modes to show different electrical parameters. Use the 'MODE' button to switch between these displays.
Available display modes include:
- Power (W): Instantaneous power consumption in Watts (0.1 - 3680 W).
- Voltage (V): Mains voltage in Volts (200 - 276 V).
- Cumulative Energy (kWh): Total energy consumed in kilowatt-hours (0.00 - 9999.9 kWh).
- Cumulative Cost (€): Total calculated cost based on energy consumption (0.00 - 99.99 €).
- Cost Rate (€/kWh): The set cost per kilowatt-hour.

Setting Cost Rate
To set the cost per kilowatt-hour (€/kWh):
- Press the 'MODE' button repeatedly until the 'Cost Rate (€/kWh)' display appears.
- Press and hold the 'MODE' button for approximately 3 seconds until the digit starts flashing.
- Use the 'UP' button to adjust the flashing digit. Press 'MODE' to move to the next digit.
- Once all digits are set, press and hold 'MODE' again to save the setting and exit.
Resetting Data
To reset all accumulated data (Cumulative Energy and Cumulative Cost), locate the small 'RESET' button (often a recessed pinhole) between the 'MODE' and 'UP' buttons. Use a thin, non-metallic object (like a paperclip) to press and hold this button for a few seconds until the display resets to zero.
