Press the dial corresponding to the parameter you wish to set (the
selection marker will move clockwise).
OR
³
Press directly the value to select it. The selection marker will go to that
value immediately.
If you want the application to provide automatic acquisition values, move
at least one dial to the Auto position. The other dials are automatically set
accordingly.
If you want to use the same values for all wavelengths of a module, select
the Apply Settings to All Wavelengths box.
Note: If your OTDR supports singlemode, singlemode live, or multimode
wavelengths, settings would be applied to either singlemode, singlemode
live, or multimode wavelengths, depending on the selected fiber type
(same settings for 50 μm and 62.5 μm).
