Edit Open the selection of mathematical functions with [Edit]:
z Extreme values (zoomed area)
Highlights the extreme values (minimum and maximum values) of the
displayed spectrum.
z Mark points
Opens an edit mode where you can highlight individual points of the
spectrum.
With the [Mark] function key you can highlight individual points.
The wavelength and measured valued are displayed at the highlighted
point.
With the [Delete] function key you can remove individual points.
z Delete all marks
Erases all highlighted points in the spectrum.
z Original
Displays the original, unedited spectrum.
z Integral
Calculates the area between the zero line and curve within a freely
selectable wavelength interval [X1,X2].
z Derivative
Calculates the derivative of the total spectrum. To calculate the second
and third derivative, the function can be carried out several times.
z Compare spectrum
Loads a second spectrum into the same diagram for direct comparison.
z Add spectrum
Adds a stored spectrum to the current spectrum.
z Subtract spectrum
Subtracts a stored spectrum from the current spectrum.
z Divide spectrum (ratio)
Divides the absorbance or % transmission values of the current spectrum
by the values of a stored spectrum
z Add fixed value
Adds a constant absorbance or % transmission value to the current
spectrum.
z Multiply fixed value
Multiplies the absorbance or % transmission values of the current
spectrum by a constant value.
Note
The addition, subtraction and division of two spectra always applies to the
common wavelength range of both spectra only.
