How To Do an Auto SmartLoop Test
1 On the home screen, tap the test setup panel.
2 On the CHANGE TEST screen, tap the button next to the Auto
SmartLoop test, then tap USE SELECTED.
If an Auto SmartLoop test is not available, tap NEW TEST to add
one to the project. Select settings as necessary on the TEST
SETUP screen. See “Settings for OTDR Tests” on page 153.
3 Select three launch cords that have the same type of fiber as
the fiber you will test.
4 On the home screen, tap the TOOLS icon, then tap Set Launch
Compensation.
5 On the SET LAUNCH METHOD screen tap SmartLoop.
6 Clean and inspect the OTDR port and connectors on the three
launch cords.
7 Make the connections shown in Figure 73.
8 Tap SET.
9 When the SET LAUNCH COMP screen shows, make sure the
tester shows the correct distances for the end of the launch
cord and the start of the tail cord.
Note
If the fibers have APC connectors, the tester
possibly will not find the correct launch and tail
events. If this occurs, do the compensation again
and select Manual Entry to enter the lengths of
the cords manually.
10 Tap SAVE.
11 Make the connections shown in Figure 74.
12 On the home screen, make sure the IDs for the fibers are
correct. The tester uses the Fiber A ID for the fiber connected
to the launch cord.
