Concentration
In concentration measurements, linearization defines the correlation between the
measured density and the concentration.
The concentration measurement is therefore a density measurement with subsequent
linearization. The calibration process is identical to density measurement.
Linearization is performed on completion of the density calibration.
Example: take the necessary value pairs from the diagram.

Linearization
Linearization table conditions
• The table can consist of up to 32 "density value : concentration (%)" pairs
• The table must decrease monotonically
• The first value in the table must correspond to the minimum density value
• The last value in the table must correspond to the maximum density value
