Brief Introduction:                     Feature:
N F-905 series are of red lighting source upon 650 nm conductor   1.FC/SC/ST ports are changeable and available to connect
for laser enitter, drived by constant current source to emit regular      detector against light leak or poor contact,further to greatly
red light. Connecting the interface in multi-mode or singal mode      decrease possible radiation to user for safety.

maintaining,producing and studying of light components .  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
Fiber Malfunction Tester         choose switch mode (Continuum or Impulse).
