3. To select another isotope from the Isotope Editing screen, click on <Open>. A list of isotopes will be
displayed.
4. Highlight the desired isotope from the Isotope List and click <Select>. The new isotope is now
displayed in the Isotope Name box. All information on the Isotope Editing screen now reflects the
new isotope.
To Add or Modify a New Isotope
Adding an isotope is most easily accomplished by modifying an existing isotope from the Isotope List.
(For example, if you want a wider window for Technetium then the factory preset value, modify
Technetium on the Isotope List so that it has a new name such as "Technetium Wide." You can then
modify the upper and lower level discriminators.)
1. Click on the <Isotope> icon in the primary tool bar. The Isotope Editing screen should now be
displayed.
2. Click on <Open>. The Isotope List should now be displayed.
3. Highlight the desired factory isotope to modify from the Isotope List and click <Select>. The new
isotope is now displayed in the Isotope Name box. All information on the Isotope Editing screen
now reflects the new isotope.
4. Click on <Add>.
5. Enter a custom name for the new isotope and modify the specifications as required.
6. Once all modifications are complete, click <Save> at the top of the isotope menu. If you do not wish
to save what you have entered or want to get out of this screen, click <Cancel> to exit without
saving.
To Edit An Isotope
With the Isotope Editing Screen displayed, clicking on <Edit> allows you to change information
associated with the currently selected isotope. For factory isotopes, you can adjust only detector efficiency
or whether to use it for Bioassay or Wipe.
For custom isotopes editing allows for adjustment of area readings, half-life gain, ROI settings, as well as
the isotope name.
1. Click on the <Isotope> icon in the primary tool bar. The Isotope Editing screen should now be
displayed.
2. Click on <Open>. The Isotope List should now be displayed.
3. Highlight the isotope to edit and click on <Edit>.
4. Make the appropriate changes to the isotope you are editing.
5. Once you have made the edits desired, click <Save> to save the edited isotope.
