6.2 알람 기능

The alarm function allows you to set custom safety ranges for each parameter (pH, TDS, Salinity, S.G, Temperature) directly within the Tuya Smart app. If any measured value falls below the lower limit or exceeds the upper limit, the app will send a notification alert to your smartphone.

6.3 데이터 내보내기

The Tuya Smart app supports exporting measurement data, typically in Excel format, for further analysis and record-keeping. Refer to the app's specific settings for data export options.

7. 교정

Regular calibration ensures the accuracy of your water quality tester. The WQM-397 supports easy calibration using standard buffer solutions.

1. 완충 용액을 준비하세요: Use the provided pH buffer powders (pH 4.00, pH 6.86, pH 9.18) to prepare standard calibration solutions according to their instructions.
2. pH 교정: Submerge the pH electrode into the first pH buffer solution (e.g., pH 6.86). Press and hold the 'TEMP/CAL' button until the calibration mode is activated. Follow the on-screen prompts or app instructions to complete the calibration for that point. Repeat for other pH buffer solutions as needed.
3. TDS/Salinity/S.G Calibration: Refer to the detailed instructions in the Tuya Smart app or the device's specific manual section for EC/TDS/Salinity/S.G calibration, as this may require specific standard solutions.
4. Rinse Electrodes: Always rinse electrodes thoroughly with distilled water between different buffer solutions and after calibration.

8. 유지관리

8.1 전극 관리

• 헹굼: Always rinse the electrodes with distilled or deionized water before and after each use to prevent contamination.
