The sensor does not need to be taken out of the medium for calibration; it can be calibrated
directly on-site in the application.
Before the calibration, ensure that the measuring gap is not fouled with deposit buildup.
If calibration takes place directly near the zero point, a new zero point is calculated based
on this calibration point. The original zero point is overwritten.
1-point calibration
The measured error between the measured value of the device and the laboratory measured
value is too large. This is corrected by a 1-point calibration.

1. Select data record.
2. Set the calibration point in the medium and enter the target sample value (laboratory
value).
The following sample values for the calibration of the CUS50D sensor can be derived from the
graphic →  21,  28:
• Measured value on the x-axis: 6 g/l
• Target sample value on the y-axis: 4 g/l
