Automatically Detecting Wavelength
Automatically Detecting Wavelength
Compatible sources (such as FOT-930, FOT-300 and FLS-300) can transmit
their wavelength values through the fiber, avoiding the need to manually
match the source and power meter wavelengths.
Note: When receiving an auto-wavelength (or Auto-ID) signal, you cannot
manually change the power meter wavelength.
To receive an auto-wavelength signal from a source:
1. Press Menu, then select Setup > Power
Meter.
OR
From the Power Meter pane, press Setup
(F1/F2 key).
2. Use the arrows to select Automatic
wavelength detection, then press Enter.
3. Connect a compatible source to your unit’s power meter port.
4. Activate the source in Auto-ID mode (FOT-930: see Using a Light
Source on page 59).
Your power meter automatically matches the source wavelength.
