VFL (Visual Fault Locator)
The Visual Fault Locator (VFL) is a visible (red) light source.
Since the light from the VFL is visible, it is useful for locating
fault points in the dead zone by visually checking the
diffusing light.
WARNING
!
NEVER look directly into the cable connector on the
unit nor into the end of a cable connected to the unit. If
laser radiation enters the eye, there is a risk of injury.
