Opening Results Files
You can open results files that are stored on your unit or on a USB memory
key. If you need more flexibility and a greater choice of report types, you
can also transfer results files to a computer onto which applications such
as EXFO FastReporter2 are installed.
To open results files:
1. From the button bar, tap Open.
2. If necessary, change the location from which the file should be
opened.
