6. Bakım

The EARU-1008 is designed for minimal maintenance. However, periodic checks are recommended:

• Cihazı temiz, toz ve kirden uzak tutun.
• Periodically inspect wiring connections for tightness and signs of wear.
• Cihazın aşırı ısınmasını önlemek için çevresinde yeterli havalandırma olduğundan emin olun.

7. Sorun Giderme

If the device is not functioning as expected, consider the following:

• Ekran Yok/Güç Yok: Check the main power supply and all wiring connections.
• Protection Trip: Identify the active protection indicator (>V, <V, >I). Check the corresponding voltage or current levels. The device will automatically reset once conditions return to normal, based on configured recovery delays.
• Faz Arızası: The device automatically detects and responds to phase failures, initiating a cut-off and auto-reset once the phase is restored.
• Yanlış Okumalar: If readings appear inaccurate, consider performing a manual error calibration as described in Section 5.3.
