3. Setup Instructions

3.1 Unpacking and Initial Inspection

• Carefully remove all components from the packaging.
• Verify that all items listed in the product description are present: 1 x water quality tester, 1 x pH probe, 1 x ORP probe, 1 x PPM/EC/Salt/SG/CF probe, 1 x temperature probe, 1 x charger.
• Inspect the device and probes for any visible damage.

3.2 Power Connection

1. Connect the power adapter to the main unit's power input port.
2. Plug the power adapter into a standard electrical outlet. The device will power on automatically.

3.3 Probe Connection

1. Carefully connect each probe (pH, ORP, PPM/EC/Salt/SG/CF, Temperature) to its corresponding BNC or designated port on the main unit, as indicated in Image 2.1. Ensure connections are secure.

3.4 Device Placement

The device features a wall-mounted design for convenient installation. Use the provided suction cups and bracket to secure the main unit near your water source (e.g., aquarium, pool).

Important Note: This tester is not waterproof. Do not let the tester get water or damp during use. Otherwise, the tester may not work normally.

3.5 App Download and WiFi Connection

1. Download the Tuya Smart app from your smartphone's app store (iOS or Android).
2. Register or log in to your Tuya Smart account.
3. Follow the in-app instructions to add a new device. Select the water quality monitor from the list of available devices.
4. Ensure your device is connected to a 2.4GHz WiFi network during the pairing process.
5. Once connected, the device will upload data in real-time to the app.

4. Operating Instructions

4.1 Basic Operation and Display

• After connecting to power, the device will automatically turn on and begin displaying readings.
• The LCD backlight display provides clear readings, supporting night monitoring.
• Use the °C/°F Switch Key to toggle between Celsius and Fahrenheit for temperature readings.

4.2 Measurement Readings

The device simultaneously displays multiple parameters. The PPM/EC/SALT/S.G/CF Switch Key (MODE) allows you to cycle through the different measurements on the rightmost display.

4.3 Calibration

Regular calibration ensures accurate readings. Refer to the specific calibration solutions and procedures for pH, ORP, and EC/TDS/Salt/CF measurements. Use the dedicated CAL keys for each parameter.

• pH Calibration: Use standard pH buffer solutions (e.g., pH 4.00, 6.86, 9.18). Follow the instructions in the app or a detailed calibration guide for your specific buffer solutions.
• ORP Calibration: Use a standard ORP calibration solution.
• EC/TDS/Salt/CF Calibration: Use a standard conductivity solution.

4.4 App Data Monitoring and Features

The Tuya Smart app provides comprehensive data monitoring and control features:

• Real-time Data: View current water quality parameters directly on your mobile phone. Data is transmitted every 15 seconds.
• Historical Data: Access daily, weekly, and monthly data curves to understand trends and water quality conditions over time.
• Alarm Settings: Set safety parameter ranges for each measurement. If parameters exceed the set values, you will receive message reminders and alarms on your phone.
• Scene Automation: Configure smart scenes based on water quality parameters (e.g., turn on a pump if pH is too high).
• Data Export: Export historical data to an Excel file or send it via email for further analysis or record-keeping.

5. Maintenance

5.1 Probe Cleaning

• Regularly clean the probes to ensure accurate readings.
• Rinse probes with distilled or deionized water after each use or before calibration.
• For stubborn deposits, gently clean with a soft brush and a mild cleaning solution specifically designed for water quality probes. Avoid abrasive materials.

5.2 Storage

• When not in use for extended periods, ensure probes are stored correctly. pH and ORP probes typically require storage in a specific solution (e.g., KCL solution) to prevent drying out. Refer to individual probe instructions for best practices.
• Store the main unit in a dry, cool place, away from direct sunlight and moisture.

6. Troubleshooting

6.1 Inaccurate Readings

• Solution: Perform calibration for the affected parameter. Ensure probes are clean and free from deposits. Check if probes are properly submerged and not damaged.

6.2 No Display/Power Issues

• Solution: Verify that the power adapter is securely connected to both the device and a working power outlet. Check the power adapter for any damage.

6.3 WiFi Connectivity Problems

• Solution: Ensure your router is broadcasting a 2.4GHz WiFi signal. Move the device closer to the router. Restart the device and your router. Re-attempt the pairing process in the Tuya Smart app.

6.4 App Not Receiving Data

• Solution: Check your internet connection. Ensure the device is still connected to WiFi (check the WiFi indicator on the device). Close and reopen the Tuya Smart app. If the issue persists, try re-pairing the device with the app.
