NOYAFA NF-905 - Manual (Page 3)

N F-905 series are of red lighting source upon 650 nm conductor
for laser enitter, drived by constant current source to emit regular
red light. Connecting the interface in multi-mode or singal mode
starts up fiber malfunction testing.
It is a indispensible tool in respects of fiber engineering,
maintaining,producing and studying of light components .
Brief Introduction:
Fiber Malfunction Tester
Feature:
1.FC/SC/ST ports are changeable and available to connect
detector against light leak or poor contact,further to greatly
decrease possible radiation to user for safety.
2.The light emitted at LD TRAP is taken on long reach and
powerful spotlight.
3.Macro energy, Strong signal, Sufficient lighting, High accuracy.
4.LED lighting for working in darkness.
5.Simple buttons for convenient using.
6.Push-pull dust cover and rubber bar for comfortable holding.
Useage:
1.Open battries cover,install in 1.5V batteries on correct positive
and negative terminals, close batteries cover . ( Notice:do not
reverse batteries)
2.Open dust cover,and pull out the rubber plug in FC port,turn on
the power with power indicator lamp working.Then, press "Red
Light" key to start up red light from port (Notice: Do not look
directly at lighting port against hurting eyes.)
3.Press"Red Light" key once more to change into lighting impulse
mode for constant flashing. (Impulse frewuency in range of 2–
3Hz or 9 Hz)
4.Press "Red Light" key again to turn off lighting source, (switch
mode :Continuum-Impulse-Continuum).
5.Connecting fiber into port and pressing " Red Light " key to
choose switch mode (Continuum or Impulse).
