previous procedure to calibrate other solution till calibration finishes. During calibration, user
could press 'END' key anytime to finish the calibration.
During calibration, each time when you change standard solution, please made sure to input
relevant STD value (pX value) in corresponding to current standard solution.
Note: When calibration of the fifth standard solution finishes, meter will stop calibration
automatically.
4.6.2.2 Setup mV Displayed Resolution
The same as 'Setup mV Display Resolution' in pH measuring
4.6.2.3 Setup pX Display Resolution
The same as 'Setup X Display Resolution' in pH measuring
4.6.2.4 Calibrate Zero Point Potential
The same as 'calibrate zero point potential' in 'pH measuring'
4.6.3 Ion Concentration Measurement
It is used to measure ion concentration of solution. Meter supports four concentration measuring
modes, including direct reading concentration mode, known addition mode, sample addition mode
and GRAN measuring mode.
4.6.3.1 Directly Reading Concentration Mode
The mode has following formula:
