Setting a Reference File or Measurement
(FR2-FC Mode)
A reference file is used to compare fibers within the same cable, monitor
fiber deterioration or compare fibers before and after installation. Once a
measurement file has been added to a project, you can set it as a reference
file. The reference file can then be used to automatically document other
measurement files (see Automatically Documenting Measurement Files
(FR2-FC Mode) on page 313).
For supported OTDR file formats, FastReporter 2 will display the reference
measurement, in red, in the Event Table. The reference measurement can
then be applied as a template (see Setting and Applying OTDR/OTDR Bidir
Reference as Template (FR2-FC Mode) on page 148). You can set a file as a
reference if the file format supports applying a reference as a template.
