Measuring Power or Loss (FPM-600 and FOT-600)

28 FPM/FLS/FOT-600

Measuring Power or Loss

6. 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 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.

 Press to switch between pre-selected wavelengths (see

Defining a List of Favorite Wavelengths on page 22).

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.
