5.2 배선 지침

Refer to the wiring diagram below for correct connection. The meter requires both a live (L) and neutral (N) connection for its own power supply and for voltage measurement. For current measurement, one of the load cables (either live or neutral) must pass through the integrated current transformer hole.

• AC 입력 볼륨 연결tage (Live and Neutral) to terminals 1 and 2 of the meter.
• Pass one of the load cables (Live or Neutral) through the current sensing hole on the right side of the meter. The direction in which the cable passes through the hole does not affect the measurement.
• 모든 연결 부분이 안전하고 적절히 절연되어 있는지 확인하세요.
• For three-phase systems, connect only one live wire and the neutral wire to the meter for measurement.

6. 운영

6.1 전원 켜기

Once properly wired and power is supplied, the meter will automatically power on and display the measured electrical parameters on its LCD screen.

6.2 디스플레이 모드

The meter cycles through different display screens, showing various parameters such as voltage, current, active power, energy, frequency, and power factor. The colorful HD LCD ensures clear readability.

6.3 Data Reset

To reset the accumulated electrical energy (kWh) data, press and hold the blue "RESET" button on the front panel for approximately five seconds. The energy value will reset to zero.

The meter automatically stores the accumulated energy data even if power is interrupted. When power is restored, it will continue to accumulate from the last saved value.

7. 문제 해결

• 디스플레이 없음: AC 입력 voltage is correctly connected to terminals 1 and 2 and within the specified range (AC 40-300V). Ensure power is supplied to the circuit.
• Current/Power Reading is Zero: Verify that one of the load cables is correctly passed through the integrated current transformer hole. Ensure there is an active load drawing current.
• 부정확한 판독: Confirm that the wiring is correct according to the diagram. Ensure the meter is not exposed to strong electromagnetic interference.
• 디스플레이 깜박임: While some minor fluctuations in decimal values are normal for real-time measurements, ensure stable power supply. If flickering is excessive or constant, recheck connections.

8. 유지관리

• 계량기를 깨끗하게 유지하고 먼지가 쌓이지 않도록 하십시오. 청소할 때는 부드럽고 마른 천을 사용하십시오. 연마성 세척제나 용제를 사용하지 마십시오.
• Regularly inspect wiring connections to ensure they remain tight and secure.
• 물리적 충격을 가하거나 기기를 떨어뜨리지 마십시오.
• No user-serviceable parts inside. Do not attempt to open or repair the meter yourself.
