4. Configuració i instal·lació

Follow these instructions carefully for proper installation of your PZEM-022 digital AC power meter.

4.1 Esquema de cablejat

Refer to the diagram below for correct wiring. Ensure all connections are secure before applying power.

Figure 3: Detailed wiring diagram for the PZEM-022 meter and CT. The load's L or N line must pass through the CT.

• The wiring does not distinguish between L (Live) and N (Neutral) lines for the meter's power input.
• The CT (Current Transformer) and input voltage connections must be correct. Do not connect the corresponding terminals incorrectly.
• One of the load's power lines (either L or N) must pass through the CT in a single loop.

4.2 Guia de vídeo d'instal·lació

Watch this video for a visual guide on how to connect the PZEM-022 meter and its current transformer.

5. Instruccions de funcionament

5.1 Interfície de visualització

The large LCD screen displays the following electrical parameters simultaneously:

• Voltage (V)
• Corrent (A)
• Potència activa (W)
• Energia (Wh)
• Freqüència (Hz)
• Factor de potència (PF)

5.2 Clearing Energy Data

To clear the accumulated energy data (Wh), follow these steps:

1. Press and hold the button on the front of the meter for approximately 5 seconds.
2. The energy number (Wh) on the display will start flashing. Release the button.
3. Press the button briefly again. The energy data will be cleared, and the flashing state will stop.
4. If no button action occurs within 5 seconds after the energy number starts flashing, the data will not be cleared, and the meter will exit the clear state.

This function allows you to reset energy consumption readings for new measurement periods.
