INFORMATION!
When the zero calibration of the sensor is done in a medium with a higher turbidity than used for
the concentration reference point, it will cause invalid mapping of sensor values to the mapped
unit (g/l). The device automatically detects this failure and will report an application error
message "sensor calibration wrong" on the message screen. The error will remain until the
sensor is correctly calibrated by the user.
