5. அமைவு வழிமுறைகள்
- மின் இணைப்பு: Plug the controller into a standard 110V AC power outlet. Turn on the device.
- மின்முனை இணைப்பு: Connect the PH electrode and the ORP electrode to their respective BNC sockets on the controller. Ensure connections are secure.
- பாதுகாப்பு உறைகளை அகற்று: Carefully remove the protective covers from both the PH and ORP electrodes. எச்சரிக்கை: 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. குறிப்பு: The mobile application is compatible with Android devices only.

6. இயக்க வழிமுறைகள்
- மூழ்குதல்: Insert the electrodes into the solution to be measured, ensuring that the measuring electrodes are fully immersed.
- அளவீடு: 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.
- நிகழ் நேர கண்காணிப்பு: The device continuously displays the PH and ORP values. No button presses are required to switch between measurements.
- மொபைல் பயன்பாட்டு கண்காணிப்பு: If configured, use the dedicated mobile application on your Android device to view real-time data and water quality changes remotely.
- வெளியீடு கட்டுப்பாடு: 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. பராமரிப்பு
- பயன்பாட்டிற்கு பிறகு: After each measurement, unplug the power supply. Clean the electrodes thoroughly with clean water (preferably distilled water) and replace their protective covers.
- மின்முனை சேமிப்பு: 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.
- நீண்ட கால பயன்பாடு: For continuous, long-term monitoring, ensure the instrument and electrodes are securely fixed in place to prevent accidental damage or displacement.
- அளவுத்திருத்தம்: 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.
8. சரிசெய்தல்
- தவறான அளவீடுகள்: Ensure electrodes are clean and properly calibrated. Check for air bubbles on the electrode surface during measurement.
- காட்சி இல்லை: Verify the power supply is connected and the device is turned on. Check for any loose connections.
- நிலையற்ற அளவீடுகள்: Ensure the electrodes are fully immersed and the solution is not agitated excessively. Allow sufficient time for readings to stabilize.
- வைஃபை இணைப்புச் சிக்கல்கள்: 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.
