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.

Description
Curve Icon
(Choice of Cursor Mode)
Choice of Cursor Mode Peak/Valley (cursor moves between minimum/maximum absorbance 
values) or Cursor Mode Tracking (cursor moves over each data point of the scan).
Arrow keys
The arrow keys are used (right/left) to move the cursor (depending on the selected mode) to the 
next data point. The data of the data point (wavelength/absorbance or transmittance value) are 
highlighted on the x and y axes. 
Note: Press any point on the curve to display the associated data.
Zoom Icon
This function is used to magnify the section of the curve in the vicinity of the cursor. The original
