Note: This option is only available when there are stored scans with the same wavelength range

and step.

λ To enter the wavelength spectrum and the scan interval

Select View

Enables the user to switch the display back and forth between the scan data tables

(wavelength/absorbance) and the graph of the curve.

Note: Select View will be activated after the first reading.

Cursor Mode

To select Track or Peak/Valley. The selection for this menu item determines to which points on

the graph the cursor moves.

Send Data To send Data to a printer, computer or USB memory stick (Type A)

Integral: On/Off The integral gives the area and the derivative of the integral gives the original function

Scale & Units
