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: 1
• Connector Type: Select the type of connector that is
on the cords you will test
