Folder icon To store the scan data
From the displayed list of stored scans, a record is selected
for use as a reference scan/superimposed scan. This can be
highlighted or shown in the background in comparison with
the actual measured scan.
Reference Off/On
Note: This option is only available when there are
stored scans with the same wavelength range and
step.

This functions as a stopwatch. It helps to make sure that the
steps of an analysis are correctly timed (e. g. reaction times,
Timer icon wait times, etc., can be exactly specified). When the
specified time has elapsed, a sound is emitted. The use of
the timer has no influence on the reading program.
Enables the switching between the display of tabular scan
data (wavelength/absorbance) and the graphical
