1. Select data record.
2. Set 3 different calibration points in the medium and specify the corresponding set
points.
A linear extrapolation is performed outside the calibrated operational range (gray line).
The calibration curve must be monotonically increasing.
The following sample values for the calibration of the CUS50D sensor can be derived from the
graphic →  23,  30:
• Measured values on the x-axis: 3 g/l, 6 g/l, 8 g/l
• Target sample values on the y-axis: 4 g/l, 4.7g/l, 6 g/l
Stability criterion
During calibration, the measured values provided by the sensor are checked to ensure they are
constant. The maximum deviations that may occur in measured values during a calibration are
defined in the stability criterion.
