5. Select the custom element type.
6. Press OK to save the changes and close the dialog box, or press Cancel
to exit without saving.
Once your custom elements are added, they become available in the list of

element type in Modifying Element Types on page 236.
The application allows you to view the pass/fail threshold for each custom
element of the test configuration even if the FR2-FC option is not activated.
If multiple iOLM measurements are selected, the application displays the
pass/fail threshold for each custom element included in each test
configuration of the selected iOLM measurements.
If the same custom element is included in more than one iOLM
measurements and the threshold values are different, the application
displays all different threshold values separated with a semicolon.
Note: You can edit the loss pass/fail thresholds for each custom element only
when the FR2-FC option or the trial is activated.
