OMNI Fiber is designed to provide a consistent,
calibrated light source for effectively measuring
signal loss in fiber optic cables. The transmitted light
can be operated continuously or modulated.
When testing loss, use the continuous light source,
when identifying fiber cables with a tone locator, use
the 2KHz modulated mode.
Press (Continuous) or (Modulated) to change the light
source.
Press or to change the wavelength.
Press to find the reference value, place it in the appropriate field,
and start calculating the loss.
