FPM-600/FLS-600
When the unit detects a modulated signal, it beeps and 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.
When power or loss is outside power limits

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 see
To receive the
auto-wavelength signal or detect the source's auto-switching
mode:
on page 29), 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
