Pulse Width
Note:
This parameter is set for [Manual] test mode only.
The OFL 200 can operate using different pulse widths. Short pulse widths provide the shortest
event and attenuation dead zones. Long pulse widths provide the best event detection on long
fi bers. We recommend setting the [Pulse Width] parameter to the lowest value that provides the
event detection range you need.
To set Pulse Width:
1 From the [Setup] screen, use either [ ] or [ ] arrow key to highlight the data fi eld beside
the [Pulse Width] label.
