- Connect the incoming Live (L) wire to the terminal marked 'L' on the input side.
- Connect the incoming Neutral (N) wire to the terminal marked 'N' on the input side.
- Connect the outgoing Live (L) wire to the terminal marked 'L' on the output side.
- Connect the outgoing Neutral (N) wire to the terminal marked 'N' on the output side.
- Prima di ripristinare l'alimentazione, verificare nuovamente che tutti i collegamenti siano ben serrati e corretti.
6. Istruzioni per l'uso
6.1 Accensione
After successful installation and wiring, restore power to the circuit. The meter's LCD display will illuminate, showing the current readings.
6.2 Modalità di visualizzazione
The meter features a dual-row display. The top row cycles through various temporary electrical parameters, while the bottom row consistently shows the total power consumption (kWh).
- Top Row (Rotating Display): Shows temporary kWh, Voltage (V), Current (A), Power (W), Power Factor (PF), and Frequency (Hz). This display automatically cycles through these parameters.
- Bottom Row (Static Display): Always shows the total accumulated power consumption in kWh. This value cannot be reset.
6.3 Reset Function for Temporary kWh
The temporary kWh reading can be reset to zero for monitoring consumption over specific periods.

Image 5: Diagram illustrating the reset function. The top display shows temporary power consumption (resettable), the bottom shows total power consumption (not resettable), and indicates to hold the reset button for 6 seconds.
- Locate the reset button on the front panel of the meter.
- Press and hold the reset button for approximately 6 seconds.
- The temporary kWh value on the top display will reset to zero. The total power consumption on the bottom display will remain unchanged.
