(1) Under the real-time test mode, the instrument will make
real-time scan for the change of the optical fiber to be test,
but not make average handling for it.
(2) Under average test mode, after the instrument scanning
tests the trace of optical fiber to be tested, make average
superposition treatment to the trace continuously according
to the set average times.
(3) Average test mode can achieve trace of higher signal to
noise ratio. Under the same condition, the noise content in
the trace received from average test is lower than that of
real-time test, and the test result is more precise.

instrument will conduct a trace analysis about the trace.
After the trace analysis is finished and the event point is
found, it will display the event information in the event table
of the main screen in accordance with the every set event
threshold; and at the same time, it will mark the location of
