Referencing Your Power Meter to a Source
To reference the power meter to a source manually:
1. Using the proper adapter, connect a light source (such as FLS-600 or
FOT-600) to the detector port of your power meter.
2. Activate the source at the desired wavelength.
3. Match the source and power meter
wavelengths:

If the source emits an auto-wavelength
signal or is in auto-switching mode (see
Automatically Detecting Wavelength on
page 29 and Using Auto-Switching Mode
on page 35), the power meter automatically matches the source
wavelength.
OR

Press to switch between pre-selected wavelengths (see
Defining a List of Favorite Wavelengths on page 22).
4. Hold down for a few seconds. The
power meter stores the currently detected
power as the new reference power.
Reference power is displayed in the top
right corner (in dBm) and current loss
reading is automatically switched to dB.
