6.5 Wavelength Scan mode – recording of absorbance and transmission
spectrums
In the Wavelength Scan mode, the absorbance of the light in a
solution over a defined wavelength spectrum is measured.
The reading results can be displayed as a curve, as percentage
transmittance (%T) or as Absorbance (Abs). The collected data
can be printed as a table or a curve.
The data is available for formatting changes. These include
automatic scaling and zoom functions. Maximum and minimum
values are determined and shown as a table.
The cursor can be moved to any point on the curve for the
purpose of reading off the absorbance or transmittance value and
