a Factory calibration
b Application calibration
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.
Factor
With the "Factor" function, the measured values are multiplied by a constant factor. The
functionality corresponds to that of a 1-point calibration.
Example:
This type of adjustment can be selected if the measured values are compared to the
laboratory values over a longer period of time and all values are too low by a constant
factor, e.g. 10%, in relation to the laboratory value (target sample value).
In the example, the adjustment is made by entering the factor 1.1.
