- MODE Button: Cycles through different measurement parameters (EC, TDS, Salt, SG). Also functions as a decrease button during settings.
- TEMP CAL/+ Button: Used for temperature calibration and as an increase button during settings.
- Wi-Fi Button: Activates or deactivates Wi-Fi connectivity for app monitoring.
- CAL Button: Initiates the calibration process for pH.
Parameter Calibration
The meter supports a 3-point calibration for pH to ensure accuracy. EC/TDS/Salt/SG calibration may also be required depending on usage.
- pH Calibration: Prepare the pH buffer solutions (pH 4.00, 6.86, 9.18). Submerge the pH electrode into the first buffer solution. Press the 'CAL' button and follow the on-screen prompts. Repeat for the other two buffer solutions.
- EC/TDS/Salt/SG Calibration: Refer to the detailed instructions in the mobile application or the full user manual for specific steps on calibrating these parameters. Note that EC solution is not included.

Mobile Application Monitoring
The meter connects to a mobile application via Wi-Fi for 24-hour online monitoring and data logging.
- Download App: Scan the QR code in the product packaging or search for the compatible app (e.g., Tuya Smart) on your smartphone's app store (iOS or Android).
- Connect to Wi-Fi: Ensure the meter's Wi-Fi function is enabled. Follow the app's instructions to connect the meter to your home Wi-Fi network.
- Monitor Data: Once connected, you can view real-time data, set alarms, and review historical data directly from your smartphone.

Maintenance
- Electrode Cleaning: Regularly clean the electrodes with distilled water to prevent buildup and ensure accurate readings. For stubborn deposits, use a soft brush or a mild cleaning solution recommended for pH/EC probes.
- Electrode Storage: When not in use, store the pH electrode in a suitable storage solution (e.g., KCL solution) or distilled water to prevent it from drying out.
- Recalibration: Calibrate the meter regularly, especially if readings appear inconsistent or after prolonged periods of non-use.
- Unit Cleaning: Wipe the main unit with a soft, dry cloth. Do not immerse the main unit in water.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate Readings | Electrodes are dirty or need calibration. | Clean electrodes and perform a 3-point calibration. |
| Display Not Working | Power supply issue or unit malfunction. | Check power connection. Ensure the correct power adapter is used. If problem persists, contact support. |
| Cannot Connect to App | Wi-Fi not enabled, incorrect network, or app issue. | Ensure Wi-Fi is enabled on the meter. Verify network credentials. Restart app and meter. |
| EC Solution Not Included | This is standard. | EC calibration solution must be purchased separately. |
