Clearing Traces from the Display
Clearing Traces from the Display
Note: This function is available in Advanced mode only.
Note: Clearing traces from the display does not delete them from the disk.
Although the test application automatically opens the last trace files used,
you can clear the screen and launch new acquisitions. If a trace you
acquired (main or reference) does not meet your requirements, you can
clear that trace and start over.
To clear traces from the display:
1. From the button bar, press Storage.
2. From the Storage dialog box, press Clear Main or Clear Reference.
If you had already acquired or modified (but not stored) some traces, a
warning message appears for each trace (even if the trace is hidden)
asking you if you want to save it or not. Press Yes to save the trace.
3. Press Close to return to the main window. You can now acquire a new
trace. For more information, see Testing Fibers in Advanced Mode on
page 37.
