Once correctly wired and mounted, restore power to the circuit. The LCD display will illuminate, showing the current energy readings.
5.2 Ifihan Lilọ kiri
The meter's display cycles through various parameters. Press the button located on the front panel to manually switch between the following readings:
- Lapapọ Agbara (kWh)
- Temporary Energy (kWh)
- Real-akoko Voltage (V)
- Real-time Current (A)
- Real-time Power (W)
The pulse LED will flash to indicate active energy measurement.
5.3 Resetting Temporary Energy (kWh)
To reset the temporary energy (kWh) reading to zero, press and hold the button on the front panel for approximately 6 seconds. Note that the total energy (kWh) reading cannot be reset.
