Results of PM measurement
The fiber under test must have only one wavelength. If there are several
wavelengths, the measurement results will NOT be valid.
To change the wavelength, press the
|F1| (WAVE)
button. The resulting calibrated wavelength
list is then shown below.
Selecting a wavelength for PM measurement
Select a wavelength by pressing the
|Up|
and
|Down|
buttons, then press the
|Shift/Enter|
button to confirm the selection. The new wavelength then appears in the top right corner of the
display. For the previous wavelength to remain effective, select a wavelength and then press the
|F1| (EXIT)
button.
