4. Setup
Follow these steps to set up your PH-803W controller:
- Power Connection: Plug the controller into a suitable AC power outlet (110V US Plug). Turn on the power.
- Electrode Connection: Connect the pH electrode to the 'PH' BNC socket and the ORP electrode to the 'ORP' BNC socket on the main unit.
- Electrode Preparation: Carefully remove the protective covers from both electrodes. Do not touch the electrode bulb with your hands to avoid contamination. The glass bulb is fragile; avoid impact damage.
- Initial Cleaning: Clean the electrodes with distilled water or alcohol. Gently wipe the plastic shell and shake off any small water droplets from the electrode tips to prevent interference with test results.
- Placement: Insert the electrodes into the solution you wish to measure, ensuring the measuring electrodes are fully immersed.
- Mounting: The controller features a wall-mounted design. Use the provided hook and suction cups to secure the unit and electrodes in a convenient location, such as near an aquarium or water tank.

5. Operating Instructions
5.1 Basic Measurement
- After connecting the electrodes and powering on the device, immerse the electrodes into the solution to be measured.
- Gently shake the electrodes to dislodge any small air bubbles that may be clinging to the tips.
- Wait for the display values to stabilize. The controller will show the real-time pH and ORP readings.
- The device is designed for continuous monitoring, providing ongoing readings without further interaction.
5.2 WiFi Connection and Mobile Monitoring
The PH-803W controller supports WiFi connectivity for remote monitoring via a mobile application. Note: The product can only be used with Android devices.
- Enter WiFi Configuration Mode: Long press the 'WIFI' button on the controller to enter WiFi network configuration mode.
- Connect to App: Follow the instructions in the mobile application to connect the device to your home or local WiFi network.
- Real-Time Data: Once connected, you can check valid data status and water quality changes from your mobile phone anywhere.

6. Maintenance
6.1 Post-Use Care
- After each use, unplug the power supply from the controller.
- Clean the electrodes thoroughly with clean water.
- Replace the protective covers on the electrodes to prevent damage and keep them moist.
6.2 Calibration
Regular calibration of the pH and ORP electrodes is essential for accurate measurements. Refer to the specific calibration instructions provided in the full manual or on the device for detailed steps. Typically, pH calibration involves using standard buffer solutions (e.g., pH 4.00, pH 6.86).

6.3 Long-Term Storage
For long-term storage, ensure the instrument and electrodes are properly cleaned and maintained. Store electrodes with their protective caps filled with appropriate storage solution (if specified) to prevent drying out.
7. Troubleshooting
If you encounter issues with your PH-803W controller, please refer to the following common problems and solutions:
- No Display/Power:
- Ensure the power adapter is securely plugged into both the controller and a working power outlet.
- Check the power outlet with another device to confirm it is functional.
- Inaccurate Readings:
- Calibrate the pH and ORP electrodes regularly using fresh calibration solutions.
- Ensure electrodes are clean and free from debris or air bubbles.
- Verify that the electrodes are fully immersed in the solution during measurement.
- Check the condition of the electrodes; they may need replacement if damaged or aged.
- WiFi Connection Issues:
- Ensure your mobile device is Android and the app is correctly installed.
- Confirm the controller is in WiFi configuration mode (long press 'WIFI').
- Check your WiFi network settings and ensure the signal is strong where the controller is located.
- Restart both the controller and your mobile device.
- Electrode Not Responding:
- Ensure the electrodes are securely connected to the correct BNC sockets.
- Inspect the electrode cables for any visible damage.
- If the electrode is old or has been stored improperly, it may need replacement.
