Measuring Power or Loss (FPM-600)
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) 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 28
and
Using Auto-Switching M o d e
on page
34), 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
21).
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.
