3.Press Zero. ”Zeroing....“ appears below the graph as the baseline 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
