Steps
1. Boot self-test
2. Measurement parameters (conductivity, TDS, salinity or temperature)
3. Select the temperature unit and reference temperature as required
4. Electrode calibration (support 1-3 point calibration)
5. Select the reading mode (automatic, timed, timed interval, or manual)
6. Select the compensation method (no compensation, linear or pure water compensation)
7. Start measurement
8. Data storage or transmission

Notice
• For samples below 20μS/cm, it is recommended to use 0.1 constant or 0.01 constant Conductivity detector Electrode measurement
• Pay attention to the battery undervoltage reminder and charge it in time
• Electrode calibration before use
• Electrode is fully immersed in the solution during measurement
• Regularly calibrate with calibrating solution
• Avoid use in extreme temperature environments
• Electrode cleaning and drying
