scan begins.
4.
Insert the prepared sample cuvette/cell into the cuvette/sample
cell holder.
5.
Press
Read
. Below the graph ”Reading“ appears and a graph
of the absorbance or transmittance values at the scanned
wavelengths is displayed continuously.
The Wavelength Scan is complete, if
•
the graph is shown full size,
•
the scaling of the x-axis fits automatically,
•
the Cursor functions in the vertical navigation bar are
highlighted.
