screen will 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.
