acquire its initial trace.
After acquiring its initial trace, the trace screen will begin to update every few seconds.
The frequency of screen updates will depend upon the selected TRACE
OPTIONS. Lowering the number of samples and/or increasing the STEP value
will increase the frequency of screen updates, but will also lower the trace
resolution.
f the screen does not appear to be changing, the characteristics of the fiber are
not changing.

When the OTDR is connected to a PC, OWLView software allows users to
display LIVE mode on the software trace screen. This enables users to view
real-time trace updates on the large PC monitor in order to better see events that
may not be visible on the OTDR LCD display.
To enable LIVE mode in OWLView software:
1)
Launch OWLView software;
2)
Click “Start Live Mode”
3)
If the OTDR is not already in LIVE mode, follow the instructions that appear on the software screen, wait for LIVE
mode on the OTDR to begin, then click “Start Live Mode” again.
When LIVE testing is complete, press
again to exit LIVE mode.
