5. Activate the source at the desired wavelength.
6. Match the source and power meter wavelengths using
Modulation detected

of fiber under test
When the unit detects a modulated signal, it displays the modulation value and
average measured power or loss (see left illustration above). You may notice a
slightly unstable last digit.
7. If necessary, change the displayed units by pressing
8. Repeat the procedure for other wavelengths.
