4.2 Awọn itọnisọna Wiring
Connect the meter according to the wiring diagram provided. The current transformer (CT) is essential for current measurement.
- So iwọn wiwọn pọtage input to the designated terminals on the meter.
- Pass the wire of the measure loop (the circuit whose current you want to measure) through the hole of the current transformer (CT).
- Connect the secondary input of the current transformer to the CT input terminals on the meter.
Important: Ensure all connections are secure and performed by qualified personnel to prevent electrical hazards.

5. Awọn ilana Iṣiṣẹ
5.1 Power On and Display
Once correctly installed and powered, the meter's HD color LCD will illuminate, displaying the six measured electrical parameters simultaneously.
5.2 Automatic Data Storage
The meter features an automatic data storage function for electrical energy readings. If power is interrupted, the last recorded energy value is saved. Upon power restoration, the meter will display this saved value and continue to accumulate energy consumption from that point.
5.3 Resetting Electrical Energy
To reset the accumulated electrical energy value (kWh):
- Locate the reset button. It is a small button positioned at the bottom right of the meter's casing.
- Using a thin, pointed object (such as a needle or paperclip), press and hold the reset button for approximately 4 seconds.
- Release the button. The electrical energy reading will reset to zero.
Image 5.1: The reset button is discreetly located on the side of the meter, requiring a small tool for activation.
