AvaRaman Operating manual AvaSoft Raman 7.3 November 2008

By clicking the menu option “View - Normalized Counts”, AvaSoft will use the calibration files to
convert the raw AD Counts into normalized counts. Normalized counts is an arbitrary unit in which
the intensity has been corrected for wavelength dependend sensitivity and nonlinear behaviour of
the detector.
2.3.3.2 View Menu: Channel
After selecting this option, a dialog is shown in which the channels to be displayed
can be selected. Since current Raman Systems are available with only one Master
channel, this option can be used only to switch the online Master spectra off.
Switching off may be helpful if you want to display only graphs that were saved
before (File-Display Saved Graph), without the online measured data for the Master
channel.
2.3.3.3 View Menu: Change Graph Scale
After selecting this option, a dialog is shown in which the
range for both X- and Y-axis can be changed. To switch to the
full scale, the View-Graphic Reset option, or the mouse
zoom-out feature can be used. By clicking the Save button in
this dialog, the settings for X-axis and Y-Axis will be saved to
a file and can be restored in the future by selecting the menu
option “View-Goto Preset Scale” or by clicking the
corresponding button in the button bar.
2.3.3.4 View Menu: Graphic Reset
When selecting this option, the graph will be reset to the default X- and Y-axes.
2.3.3.5 View Menu: Autoscale Y-axis
By using this option, the graph will be rescaled on-line. A maximum signal will be shown at about
75% of the vertical scale.
2.3.3.6 View Menu: Goto Preset Scale
By clicking this menu option, the scale for X- and Y-axis will be set to a range that has been set
before. The same result can be achieved by clicking the Goto Preset Scale Button in the button bar.
2.3.3.7 View Menu: Display Wavelength (nm) at X-Axis
Default, the spectral data are shown versus Raman Shift in cm -1 . After the menu option ‘Display
wavelength (nm) at X-axis’ is clicked, the wavelength in nanometers is shown at the X-axis and a
checkmark appears in front of the menu option. To return to Raman Shift, the menu option needs to
be clicked again, after which the checkmark disappears and the X-axis returns to display in cm -1 .
