Measurement mode is selected.

The wavelength is shown in the left bottom display field
and active immediately after selection:
Enabling Auto-Lambda mode
Auto- is a special feature developed by JDSU that
allows you to identify wavelengths automatically. To do
this, the signal is modulated at a certain frequency (by a
light source equipped with AUTO-, such as a JDSU
OLS-55/-56), which can be detected by a JDSU ORL-55.
Wavelengths cannot be reliably detected if:
• the receive level is too low,
• wavelength encoding cannot be detected due to
interference
• you are measuring the absolute level of a system that
does not have wavelength encoding that matches
JDSU power sources.
To switch Auto- mode on/off:
1. Select Select Auto-in the CONFIGURATION menu.
The AUTO-menu is displayed.
2. Select ENABLE to switch on Auto-
