How to Test Your Test Reference Cords

1. Set Up the Tester
1-1 Turn on the tester. Wait for a minimum of 5 minutes for
the tester to become stable. Wait for a longer time if the
tester is much colder or hotter than the work area.
1-2 Turn the rotary switch to SETUP, then make these
settings:
• Test Limit: Select the applicable limit:
• Fiber Type: Select the type of cable you will test.
This sets the index of refraction (n). The test limits
shown above use n to calculate the length of the
fiber, then they use the length to calculate the limit
for loss. Thus, you must use the correct value of n to
get an accurate measurement of loss. If you cannot
find the correct fiber type, you can enter the value
of n for your fiber on tab 3 of the setup menus. Get
the value of n from the cable vendor.
• Remote End Setup: Loopback
• Bi-Directional: Yes
• Number of Adapters: 2 (see note below)
• Connector Type: Select the type of connector that is
on the cords you will test
• Test Method: 1 Jumper
Note
Though this procedure uses 1 adapter, use “2” for
the Number of Adapters setting. Ignore the test
limit that the tester uses, and compare the loss
measurements to the values given in step 5.
