Notice
• For samples below 20μS/cm, it is recommended to use 0.1 constant or 0.01 constant Conductivity detector Electrode measurement
• Make sure Electrode is clean and free of contamination before use
• Standard calibrating solution should be used when calibrating
• Avoid use in extreme temperature environments
• Check Electrode status regularly and replace if necessary
• Please ensure that the dedicated communication software is installed correctly when transferring data
• Please confirm that the printer is connected normally when printing.
Be aware of capacity limitations when storing data
• Please follow the operating instructions when upgrading the firmware
