5. Hướng dẫn thiết lập
- Kết nối nguồn điện: Plug the controller into a standard 110V AC power outlet. Turn on the device.
- Kết nối điện cực: Connect the PH electrode and the ORP electrode to their respective BNC sockets on the controller. Ensure connections are secure.
- Remove Protective Covers: Carefully remove the protective covers from both the PH and ORP electrodes. Thận trọng: Avoid touching the glass bulb of the electrode with bare hands, as it is fragile and can be damaged by impact or contamination.
- Initial Electrode Cleaning: Before first use, or if the electrodes have been stored dry, rinse them with distilled water or alcohol. Gently wipe the plastic shell and shake off any small water droplets from the electrode tip to prevent interference with test results.
- WiFi Configuration (Optional): The device supports WiFi connectivity for real-time monitoring via a mobile application. Long press the 'ESC WIFI' button to enter WiFi network configuration mode. Follow the instructions in the mobile application to connect the device to your network. Ghi chú: The mobile application is compatible with Android devices only.

6. Hướng dẫn vận hành
- Sự đắm chìm: Insert the electrodes into the solution to be measured, ensuring that the measuring electrodes are fully immersed.
- Đo lường: Gently shake the electrodes to dislodge any small air bubbles that may be clinging to the electrode surface. Wait for the display numbers to stabilize before taking a reading. The PH and ORP values will be displayed simultaneously.
- Giám sát thời gian thực: The device continuously displays the PH and ORP values. No button presses are required to switch between measurements.
- Mobile App Monitoring: If configured, use the dedicated mobile application on your Android device to view real-time data and water quality changes remotely.
- Kiểm soát đầu ra: The two output power sockets can be used to connect and control external devices (e.g., solenoid valves, pumps) based on the measured PH and ORP values, according to your configured settings.

7. Bảo trì
- Sau khi sử dụng: After each measurement, unplug the power supply. Clean the electrodes thoroughly with clean water (preferably distilled water) and replace their protective covers.
- Lưu trữ điện cực: Store electrodes with their protective caps filled with a suitable storage solution (e.g., KCL solution) or distilled water to prevent drying out. Never store electrodes dry.
- Sử dụng lâu dài: For continuous, long-term monitoring, ensure the instrument and electrodes are securely fixed in place to prevent accidental damage or displacement.
- Sự định cỡ: Regular calibration of the PH and ORP electrodes is essential for maintaining accuracy. Refer to the calibration section (if available in a separate guide) or the device's on-screen prompts for calibration procedures.
KHAI THÁC. Xử lý sự cố
- Đọc không chính xác: Ensure electrodes are clean and properly calibrated. Check for air bubbles on the electrode surface during measurement.
- Không hiển thị: Verify the power supply is connected and the device is turned on. Check for any loose connections.
- Đọc không ổn định: Ensure the electrodes are fully immersed and the solution is not agitated excessively. Allow sufficient time for readings to stabilize.
- Sự cố kết nối WiFi: Confirm your WiFi network is active and the password is correct. Ensure the device is within range of the WiFi router. Remember the mobile app is for Android devices only.
- Electrode Damage: If readings remain erratic or impossible to calibrate, the electrodes may be damaged or have reached the end of their lifespan and require replacement.
