Principle
Electrode measurement converts the potential change in the solution into the corresponding pH value, pX value or Ion concentration value. Intelligent endpoint determination technology, combined with automatic temperature compensation and standard buffer solution identification, ensures measurement accuracy. Built-in multiple ion modes and measurement algorithms support accurate analysis of different application scenarios.
Steps
1. Power on and perform self-diagnosis
2. Measurement parameters and resolution
3. Calibrate Electrode as needed (support 1-5 point calibration)
4. Measurement mode (direct reading concentration method, standard addition method, sample addition method or GRAN method)
5. Set the temperature unit and compensation method
6. Take measurements and read the results
7. Storage or transmission of data
8. Shut down after use or set automatic shutdown
Notice
• Make sure Electrode is intact and connected correctly before use
• Use standard buffer solutions for calibration and ensure accurate identification
• Pay attention to the temperature compensation setting during measurement to avoid the influence of Ambient Temperature
• Regularly Clean Electrodes and Accessories to Maintain Instrument Protection Ratings
• Ensure stable interface connection during data transmission
• Follow the operation guide when upgrading the firmware to avoid interruptions
• Pay attention to capacity limitations when storing data and back up important data in a timely manner
