5.5 Auto-wavelength Recognition
Press the "TWIN" key to turn on and off the auto-wavelength recognition function.
Note:
1). It is suggested to turn off the "TWIN" code when you do not use it. The optical
power output of the laser source will be fluctuated.
2). The function of "TWIN" and Modulation cannot work together. When the
"TWIN" is on, the modulation of the laser source module is closed automatically.
3). The wavelength will be shifted automatically according to the recognition
when the "TWIN" of the power meter module is on. The modulated signal of
270Hz, 1kHz and 2kHz cannot be recognized and received.
