6.4. Calibration
Regular calibration of the pH and other probes is essential for maintaining accuracy. Refer to the detailed calibration instructions within the Tuya app or the included English instruction manual for specific steps using calibration solutions (not included).
7. Maintenance
- Probe Cleaning: Regularly clean the sensor probes to prevent buildup that can affect accuracy. Use distilled water or a mild cleaning solution recommended for pH probes.
- Storage: When not in use for extended periods, store the probes in a suitable storage solution (e.g., KCL solution for pH probes) to keep them hydrated and extend their lifespan.
- Main Unit Care: Keep the main unit dry at all times. Avoid exposing it to water or high humidity. Clean the exterior with a soft, dry cloth.
- Calibration: Perform calibration regularly as per the operating instructions to ensure accurate readings.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate readings | Probes are dirty or need calibration. | Clean probes and perform calibration. |
| Device not connecting to Wi-Fi/Bluetooth | Incorrect pairing procedure, Wi-Fi signal weak, or app issue. | Ensure Wi-Fi is 2.4GHz, restart device and router, re-attempt pairing in app. |
| No display on main unit | No power or faulty power adapter. | Check power connection, try a different outlet, ensure adapter is working. |
| App not receiving data | Device not connected, app permissions, or internet connectivity issue. | Verify device connection in app, check app permissions for network access, ensure stable internet connection. |
