5. Pemasangan

The KETOTEK D52-2047 is designed for easy DIN rail installation. Follow these steps carefully:

1. Penyediaan: Ensure the main power supply is turned off before beginning installation.
2. Pemasangan: Attach the meter to a standard 3.5cm DIN rail. The meter's dimensions are 5.4 x 6.4 x 8 cm, with a 3.5cm standard DIN-rail installation width.
3. Pendawaian: Sambungkan voltage input to terminals 1 and 2. For current measurement, pass one of the phase or neutral conductors (L1, L2, L3, or N in a three-phase system, or L/N in a single-phase system) through the designated hole on the meter. It is not necessary to distinguish between L and N when passing the wire through the hole.
4. Pengesahan: After wiring, double-check all connections for security and correctness before restoring power.

6. Operasi

Once installed and powered, the meter will display various electrical parameters on its LED screen.

6.1. Paparan Lebihview

The meter features a clear LED display with red and green segments. The red segments typically show voltage and current, while the green segment shows energy and active power. Indicators for Power Factor (cosφ), Cumulative Time (h), and Electrical Energy (kwh) are also present.

6.2. Function Conversion and Data Reset

The 'SAM CK' button on the front panel serves two primary functions:

• Menukar Paparan: Press the 'SAM CK' button briefly to cycle through the display of Power Factor (cosφ), Cumulative Time of Electrical Energy (h), and Electrical Energy (kwh). The corresponding red LED will illuminate to indicate the currently displayed parameter.
• Tetapkan Semula Data: To reset the electrical energy (kwh) value, press and hold the 'SAM CK' button for five seconds while the meter is displaying electrical energy. The meter will then reset the accumulated energy data.

7. Penyelenggaraan

To ensure optimal performance and longevity of your KETOTEK D52-2047 Digital AC Power Meter, follow these maintenance guidelines:

• Pastikan meter bersih dan bebas daripada habuk dan kelembapan. Gunakan kain lembut dan kering untuk pembersihan.
• Avoid exposing the device to extreme temperatures, direct sunlight, or corrosive substances.
• Do not attempt to open or repair the meter yourself, as this will void the warranty and may pose a safety risk.

8. Penyelesaian masalah

If you encounter issues with your KETOTEK D52-2047, consider the following basic troubleshooting steps:

• Tiada Paparan: Check if the power supply is connected correctly and within the specified voltage range (AC 80V-300V). Ensure all wiring is secure.
• Bacaan yang salah: Verify that the current sensing wire is correctly passed through the meter's hole and that only one conductor is used for measurement.
• Data Tidak Ditetapkan Semula: Ensure you are pressing and holding the 'SAM CK' button for the required five seconds while the electrical energy (kwh) is displayed.
