5. Instalacija
The KETOTEK D52-2047 is designed for easy DIN rail installation. Follow these steps carefully:
- Priprema: Ensure the main power supply is turned off before beginning installation.
- Montaža: 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.
- Ožičenje: Povežite AC 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.
- Potvrda: After wiring, double-check all connections for security and correctness before restoring power.

6. Operacija
Once installed and powered, the meter will display various electrical parameters on its LED screen.
6.1. Display Overview
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.

Figure 6: Display elements showing Power Factor/Voltage, Timing/Current, and Energy/Power displays, along with the function conversion button.
6.2. Function Conversion and Data Reset
The 'SAM CK' button on the front panel serves two primary functions:
- Promjena prikaza: 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.
- Vraćanje podataka na zadano: 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. Održavanje
To ensure optimal performance and longevity of your KETOTEK D52-2047 Digital AC Power Meter, follow these maintenance guidelines:
- Keep the meter clean and free from dust and moisture. Use a soft, dry cloth for cleaning.
- Izbjegavajte izlaganje uređaja ekstremnim temperaturama, direktnoj sunčevoj svjetlosti ili korozivnim supstancama.
- Do not attempt to open or repair the meter yourself, as this will void the warranty and may pose a safety risk.
8. Otkrivanje problema
If you encounter issues with your KETOTEK D52-2047, consider the following basic troubleshooting steps:
- Bez prikaza: Check if the power supply is connected correctly and within the specified voltage range (AC 80V-300V). Ensure all wiring is secure.
- Netačna očitanja: Verify that the current sensing wire is correctly passed through the meter's hole and that only one conductor is used for measurement.
- Data Not Resetting: Ensure you are pressing and holding the 'SAM CK' button for the required five seconds while the electrical energy (kwh) is displayed.
