This dialog defines functions used on each range, and the overall formula combining the functions.
To create a formula, click on the function, then on the desired region. Add another segment to the
formula using provided operands and constants. The created formula is listed below functions and
ranges.
To apply the formula on the calibration spectra:
1. Click on Set Formula and then on Close. The plot shows the trend resulting from the created
formula applied on the calibration spectra.
2. Click on the blue “Save” icon to save the formula. The created formula can be used in
