Frederick Engineering FFL-310
The Visual Fault Locator is equipped with a 650 nm high power visible laser diode, which can be operated in CW (continuous) or MOD (1 Hz modulation) mode. There are two LED indicators, RED and GREEN: The RED one shows the operating mode of the Laser Diode output signal, and the GREEN one indicates low battery level. FFL-210 series are housed in a pocket-size, rugged brass casing, and comes with a carrying pouch while FFL-310 series are in a
card-style compact design.
