2. Click the name of the tab that contains the features you want to use, or
click the Open button to open an experiment file.
If you want to align or reset the spectrometer or check the operation of
spectrometer components, click the Diagnostic tab.
Note
The spectrometer power should be on for at least 15 minutes (1 hour or longer for
best results) before you perform an alignment. ▲
If you click the Open button, the Open Experiment dialog box lists files of the
Experiment Files (*.EXP) file type. Type the name of the experiment file you
want to open or select a file from the list by clicking its filename. You can
change directories or drives to locate the file. The example experiment files
provided with OMNIC are in the C:\My Documents\OMNIC\Param directory
(or other location where you installed OMNIC).
Note
Note
You can open a parameter file from an early version of OMNIC (3.0 or earlier) by
first selecting the Parameter Files file type (*.PRM) in the dialog box. After you
open the file, its name will appear in the title bar with the extension .EXP and will be
saved with that extension if you save the file. This prevents overwriting the
parameter file. ▲
The experiments shown in the Experiment drop-down list box (if available) are those
in the current experiment directory that have been opened by using Experiment
Setup or by installing a Smart Accessory. If the current experiment directory is
OMNIC\Param, the Default experiment provided with OMNIC is also shown. ▲
Select the parameter groups you want included when the experiment is opened.
To select a parameter group, turn on its check box in the Groups box. The
Collect group contains parameters on the Collect tab; the Bench group contains
parameters on the Bench tab; the Search group contains parameters in the
Library Setup dialog box; and the Series group contains parameters in the
optional Series Setup dialog box. If you don’t include a group, those parameters
will not be changed from their current settings in OMNIC. The parameters on
the Quality and Advanced tabs are always changed to the settings in the
experiment file you open.
When you have finished selecting the experiment file and parameter groups,
choose OK. The experiment file is opened and the parameter settings are
changed as specified. If you selected a group that was not saved in the
experiment file, a message informs you.
3. Change the parameter settings as desired, or use the Diagnostic tab
features.
Important
Set Gain to 1 on the Bench tab before clicking the Align button on the Diagnostics
tab to align the spectrometer. ▲
4. When you are finished setting the parameters, you can save your settings
in an experiment file.
Note
If you have the DS option, you may be prompted to digitally sign a file
during this step. Follow the instructions that appear on the screen. Also, if Prevent
Overwriting Of Files is turned on in the Security options (available through
Options in the Edit menu), the Save Experiment As dialog box always appears
when you click the Save button (see below). ▲
