3.8 Scanning for Events
The ‘SCAN’ feature is provided as a troubleshooting mode to
allow the user to quickly find potential trouble spots along the
fiber.
SCAN searches only for events greater than the threshold value
selected during SETUP. The threshold can be set to 0.25, 0.50,
1.00, 2.00, or 4.00 dB. If events are found, their location and
value will be displayed.
3.8.1 HR, MM, DM and DS Models
Select ‘SCAN’ and the following screens will appear;
then:
The event measurement sequence takes approximately 1-2
minutes depending on fiber length, and number of splices.
The minimum distance required between reflective events to
obtain individual splice loss measurements is 30 meters. If the
events are closer than 30 meters to each other then the splice
values will be added together, and represented as a single
event. At this point, the user may wish to print out the trace or
transfer it to a computer for a more detailed look at this event
using PCPLOT3 software.
Typical events above the threshold value will appear as follows:
