After a time scan has been completed, the time and the 
absorbance/transmittance data are displayed as a curve.

Where the cursor is positioned on the curve, the elapsed time up to 
this point and the corresponding absorbance are highlighted.

Delta mode: A second cursor is highlighted. The position of the fixed cursor was previously 
defined in Cursor Mode Single. Use the active cursor to select any point on the measurement 
curve. The difference to the fixed cursor is shown on the curve. The delta values are 
correspondingly highlighted and displayed on the x and y axes.
The gradient of the curve and the correlation coefficient (r

2

) between the cursor points in the 

Delta mode are shown under the curve.
Cursor Mode Single: The cursor moves to each selected measurement point of the scan.

The arrow keys (right/left) are used 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.

This function is used to magnify the section of the curve in the vicinity of the cursor. The original 
curve size can be restored by pressing the zoom icon again.
