Description
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).
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.

function:
close the cell compartment cover.
"Zeroing" is shown below the graph as the baseline scan
begins.
and close the cell compartment cover.
Under the graph, the display "Reading..." appears, and a
graph of the absorbance or transmission values for the
scanned wavelengths is continuously displayed.
• the graph is shown full-size,
• the scaling of the x-axis occurs automatically,
• the Cursor functions in the vertical navigation bar are
