6. Operation
6.1 Taking Measurements
Once connected to the app, immerse the meter's probe into the water sample. The app will display real-time measurements for pH, TDS, EC, ORP, and Temperature. The mobile phone comprehensively displays all measurement functions, and the data is clear at a glance.
6.2 App Functions
- Data Display: View current readings for all parameters.
- Data Storage: Data can be saved automatically or manually. The saved data can be exported to Excel and shared.
- Parameter View: Access detailed product parameter information.
- Function Setting: Adjust various settings, including setting upper and lower limits for pH and TDS/EC. If a value exceeds the set range, the interface will display a red warning.
- Calibration Record: View past calibration records.

7. Calibration
The BLE-YC01 supports 5-point automatic calibration and is equipped with calibration powder. You can select Asia standard/EU standards in the app.
7.1 pH Calibration Methods
- Asia Standard: pH 4.00, pH 6.86, pH 9.18
- EU Standards: pH 4.00, pH 7.00, pH 10.01
Follow the in-app instructions for the calibration process. Ensure you use the correct calibration solutions for accurate results.

8. Maintenance
8.1 Battery Replacement
When the battery needs replacement, follow these steps:
- Open the battery compartment.
- Replace the old batteries with new ones.
- After replacing the battery, be sure to tighten the cover securely before putting it into the water. Failure to tighten the cover may cause water ingress and damage the device.

9. Troubleshooting
9.1 App Connection Issues
Q1: Why can't the app connect to Bluetooth?
- A1: Please long press the Bluetooth icon on the meter. If it displays the Bluetooth symbol, then open the phone's Bluetooth settings to connect.
- A2: Please allow the app location permission when first opening the app.
9.2 Water Ingress Prevention
- Do not remove the rubber ring from the probe unit.
- Do not remove the protection cover when there is water inside the probe unit.

10. Important Notes
- The water in swimming pools should typically be between 6.5-8.5 pH and ORP should be between 487-840mV. The chlorine value will be displayed normally.
- Chlorine will not be displayed if either value is out of range.
- If the pH value is lower than 6.5, it indicates that the water quality is too acidic and contains impurities, requiring disinfectant water for disinfection.
- If the ORP value is above 850mV, it means that the disinfectant has been added too much, and it is necessary to add water or change the water for neutralization.
- Only support test swimming pool water quality for chlorine and ORP measurements.
- Please be sure to tighten the cover when using it, otherwise it is easy for water to enter.
