6. 사용 설명서
6.1 전원 켜기
After completing all wiring, apply power to the meter. The LED displays will illuminate, showing the current Process Value (PV) and potentially a Set Value (SV).
6.2 버튼 기능
- SET 버튼: 파라미터 설정 모드로 진입하고 선택 사항을 확인하는 데 사용됩니다.
- <<RST button: Used to shift digits during value setting or to reset certain functions.
- Up (↑) button: 값을 증가시키거나 메뉴 옵션을 탐색하는 데 사용됩니다.
- Down (↓) button: 값을 줄이거나 메뉴 옵션을 탐색하는 데 사용됩니다.
6.3 Basic Operation (General)
While specific programming steps are not detailed in the provided information, typical operation involves:
- Viewing PV/SV: The main display shows the current Process Value (PV). The smaller display shows the Set Value (SV), which might be an alarm setpoint or other configured parameter.
- 설정 매개변수: Press the SET button to enter the parameter setting mode. Use the Up/Down arrows to select parameters and adjust their values. Use the <<RST button to shift between digits when setting numerical values. Press SET again to confirm and save changes.
- 알람 기능: The AL1 and AL2 indicators will light up when the measured PV exceeds or falls below their respective setpoints, triggering the corresponding relay outputs.
For detailed parameter configuration, refer to the full product manual (if available from the manufacturer) or contact technical support.
7. 유지관리
- 청소: 디스플레이를 부드럽게 닦아주세요.asin부드럽고 마른 천으로 닦아주세요. 연마성 세제나 용제는 사용하지 마세요.
- 연결 확인: 모든 배선 연결부를 정기적으로 검사하여 안전하고 부식되지 않았는지 확인하세요.

8. 문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 미터의 전원이 켜지지 않습니다. | 전원 공급이 없거나 배선이 잘못되었습니다. | Check power connections (Terminals 1, 2) and ensure voltage는 90-265V AC/DC 범위 내에 있습니다. |
| Display shows "----" or erratic readings. | Incorrect sensor wiring, sensor malfunction, or wrong input type selected. | Verify sensor connections (Terminals 9-12) and ensure the sensor is functioning correctly. Check meter configuration for correct input signal type. |
| Alarm outputs (AL1/AL2) not activating. | Alarm setpoints incorrect or relay wiring issue. | Check alarm setpoints (SV) and ensure they are configured correctly relative to the PV. Verify wiring to external alarm devices (Terminals 5-8). |
| 부정확한 판독값. | Sensor calibration issue or environmental interference. | Calibrate the sensor if possible. Ensure the meter is not exposed to strong electromagnetic interference. |
9. 사용자 팁
- Input Signal Selection: Before connecting your sensor, ensure the meter is configured for the correct input signal type (mV, mA, or V) to avoid incorrect readings or potential damage.
- 명확한 라벨링: For complex setups, clearly label all wires connected to the terminal block to simplify future troubleshooting or maintenance.
- 테스트 알람: After setting alarm points, perform a test to ensure the relay outputs activate as expected.
