Info

If at any time the system conditions have changed, making the current spectral quality reference spectrum no longer appropriate for checking background spectra, use this command to assign a new spectrum. Note You can display the current spectral quality reference spectrum by using Display Spectral Quality Reference in the Collect menu. See “Displaying the spectral quality reference spectrum” for details. ▲ Assign a new spectral quality reference spectrum 1. Select the experiment whose spectral quality reference spectrum you want to assign. See “Selecting an experiment” if you need help. 2. Select the displayed background spectrum you want to designate as the spectral quality reference spectrum. You can collect a background spectrum for this purpose or open one that is stored on a disk. 3. Choose Set Spectral Quality Reference from the Collect menu. Using the advanced diagnostics Use Advanced Diagnostics in the Collect menu to troubleshoot problems with the spectrometer. Use the advanced diagnostics Choose Advanced Diagnostics from the Collect menu. Follow the instructions that appear on the screen. For more detailed instructions, click the Help button in the Diagnostics window. 160 Thermo Nicolet
View Use the commands in the View menu to look at your spectral data in different ways. The primary use of each command is summarized in the following table: To do this... Undo display limit changes in a spectral window. Restore display limit changes reversed with Undo Limit Change. Set the display parameters for a spectral window. Stack spectra in a spectral window. Overlay spectra in a spectral window. Hide a spectrum from view. Adjust the vertical scale of spectra so that they fit their panes. Display spectra using the lowest and highest Y-axis display limits. Display spectra using the Y-axis display limits of a selected spectrum. Display spectra vertically offset. Specify X-axis and Y-axis display limits for spectra. Display spectra full scale automatically after displaying a different spectral region. Display a set of symbols for adjusting the display of spectra in spectral windows. Display the toolbar for the current configuration. Use this command... Undo Limit Change Redo Limit Change Display Setup Stack Spectra Overlay Spectra Hide Spectra Full Scale Common Scale Match Scale Offset Scale Display Limits Automatic Full Scale Roll/Zoom Window Toolbar You can customize the way OMNIC displays spectra by setting options using the Options command in the Edit menu. See “Customizing OMNIC by setting options” in the “Edit” chapter for details. Undoing display limit changes Undo Limit Change in the View menu lets you quickly undo changes you have just made to the display limits of a spectral window. You can undo up to six consecutive changes, one at a time, if you have not performed other operations since making the changes. The display limit changes that you can undo include those made using the following features: • view finder • Redo Limit Change • Match Scale • selection tool • Full Scale • Offset Scale • Roll/Zoom window • Common Scale • Display Limits OMNIC User’s <strong>Guide</strong> 161
