Using Auto-Switching Mode
In auto-switching mode, your source

compatible power meter displays the power
value for each wavelength one at a time. The
wavelength value appearing on the display
changes every two seconds.
The unit will show the source's favorite wavelengths one at a time (see
Defining a List of Favorite Wavelengths on page 33).
To activate auto-switching mode:
1. Press
to activate the source.
2. Press
to switch between available modulations until the Auto
indicator blinks on your display.
