Automatic span calibration
1.
Set the calibration mode to "AUTO" on the Calibration Setting screen.
Change other settings as needed.
Note
The value set in [Span Point] in the calibration settings must be adjusted based on the extraction
ratio.
For example, when the extraction ratio is solvent:water = 1:2, set 1/2 the value of the actual
concentration of the span liquid for calibration in [Span Point] in the calibration settings.
