Calibration
The spectrometer offers a variety of options for an application-specific calibration. Each
parameter can be calibrated individually.
Example: It is possible to calibrate the turbidity with an offset and the COD with a factor.
• The use of the offset calibration and factor calibration is recommended.
• Do not use multiple point calibration in combination with the factor calibration or offset
calibration.
If it is not possible to bring the parameters to the process values using these methods, an
application-specific model adjustment is recommended.

Contact your Hauser representative for information on application-specific
model adjustments.
Offset
Measured values that always deviate by a constant value can be corrected with an offset
calibration (e.g. if the measured values for TOC are always 1 mg/l (1 ppm) above the
laboratory value).
With the "Offset" function, the measured values are offset by a constant amount (added or
subtracted).

Factor
With the "Factor" function, the measured values are multiplied by a constant factor. The
functionality corresponds to that of a 1-point calibration.
