for the tester to become stable. Wait for a longer time
if the tester is much colder or hotter than the work
area.

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.
