5. 설치
The KETOTEK D52-2047 is designed for easy DIN rail installation. Follow these steps carefully:
- 준비: Ensure the main power supply is turned off before beginning installation.
- 설치: 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.
- 배선: AC 권을 연결하십시오tage 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.
- 확인: After wiring, double-check all connections for security and correctness before restoring power.

6. 운영
Once installed and powered, the meter will display various electrical parameters on its LED screen.
6.1. 디스플레이 오버view
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:
- 디스플레이 전환: 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.
- 데이터 재설정: 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. 유지관리
To ensure optimal performance and longevity of your KETOTEK D52-2047 Digital AC Power Meter, follow these maintenance guidelines:
- 계량기를 깨끗하게 유지하고 먼지와 습기가 없도록 하십시오. 청소할 때는 부드럽고 마른 천을 사용하십시오.
- 기기를 극한 온도, 직사광선 또는 부식성 물질에 노출시키지 마십시오.
- Do not attempt to open or repair the meter yourself, as this will void the warranty and may pose a safety risk.
8. 문제 해결
If you encounter issues with your KETOTEK D52-2047, consider the following basic troubleshooting steps:
- 디스플레이 없음: Check if the power supply is connected correctly and within the specified voltage range (AC 80V-300V). Ensure all wiring is secure.
- 잘못된 판독: Verify that the current sensing wire is correctly passed through the meter's hole and that only one conductor is used for measurement.
- 데이터가 초기화되지 않음: Ensure you are pressing and holding the 'SAM CK' button for the required five seconds while the electrical energy (kwh) is displayed.
