6. Persediaan dan Pemasangan
Penting: Pastikan semua kuasa diputuskan sebelum meneruskan pemasangan.
- Pemasangan: The EARU-1006 is designed for 35mm DIN rail mounting. Snap the meter onto the DIN rail securely within your electrical panel.
- Pendawaian: Refer to the wiring diagram below for correct connection. This is a single-phase, 2-wire direct connection meter.
- Connect the Live (L) input wire to the designated 'L In' terminal.
- Connect the Neutral (N) input wire to the designated 'N In' terminal.
- Connect the Live (L) output wire to the designated 'L Out' terminal.
- Connect the Neutral (N) output wire to the designated 'N Out' terminal.
- Hidupkan kuasa: Once all connections are secure and verified, restore power to the circuit. The LCD display should illuminate and begin showing readings.

7. Arahan Operasi
The energy meter operates automatically once powered on. The LCD display continuously cycles through or shows multiple parameters simultaneously.
- Reading Parameters: The display shows Voltage (V), Current (A), Power (W), Power Factor (PF), Frequency (Hz), and Kilowatt-hour (kWh).
- kWh Reading: The meter records total kWh consumption. This reading is permanent and accumulates over time.
- Tetapan Semula kWh: The meter features a manual reset function for the kWh reading. Consult the device's physical buttons or specific instructions on the meter itself for the reset procedure. Typically, a long press on a designated button (if present) will reset the temporary kWh value. The total kWh value is usually non-resettable.
8. Penyelenggaraan
- Pembersihan: Gunakan kain lembut dan kering untuk membersihkan bahagian luar meter. Jangan gunakan pembersih atau pelarut yang kasar.
- Pemeriksaan: Periodically inspect the wiring connections to ensure they are tight and free from corrosion.
- Persekitaran: Pastikan persekitaran operasi kekal dalam julat suhu dan kelembapan yang ditetapkan.
9. Penyelesaian masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Paparan kosong | No power supply; Incorrect wiring | Check power connections and ensure power is supplied. Verify wiring against the diagram. |
| Bacaan yang salah | Incorrect wiring; Faulty connection | Double-check all wiring connections. Ensure wires are securely fastened. |
| kWh not accumulating | No load connected; Meter malfunction | Ensure there is an active electrical load connected through the meter. If problem persists, contact support. |
