The job settings are saved with test results to identify the job site, the cables tested, and
the test direction. Before you run a test you will save, verify that the job and fiber ID
information is correct. See Chapter 2 for details.
Select a fiber type that is appropriate for the type you will test. You can select factory-
installed fiber types or custom types, which you configure with the Edit Custom Test Limit
function in FUNCTIONS. See Chapter 9 for information on creating custom fiber types.
When MANUAL CABLE SETTINGS is disabled, the n values depend on the selected fiber
type. When MANUAL CABLE SETTINGS is enabled, the tester enters default values that
you can change manually.
The n values defined in the fiber types are suitable for most applications. Minor
differences between the tester's n and a fiber's actual n usually do not make enough
difference in length to fail a fiber.
Increasing n decreases the reported length.
The tester compares the loss/length test results to the selected test limits to produce PASS
or FAIL results. You can select factory-installed limits or custom limits configured with the
Edit Custom Test Limit function in FUNCTIONS. Custom limits are marked with asterisks (*).
See Chapter 9 for information on creating custom test limits.
Select a fiber type before selecting a test limit. The fiber type determines which test
limits are available.
