Using a Reference Trace
Using a Reference Trace
Setting a measurement as a reference allows you to test fibers and
compare them to a reference trace that was previously acquired and
analyzed.
You must first open your reference trace (newly acquired and saved trace
or open trace file).
The reference measurement in memory will be closed if the option is
deactivated.
Note: You cannot edit a reference trace.
To set a measurement as a reference:
1. From the Main Menu, select the User Preferences button.
2. Select the General tab.
3. Under File Functionalities, select the Allow using reference
measurements box.
4. Tap OK to return to the main window.
You can now select the reference trace.
