Using Auto-Switching Mode

Note: Auto-switching mode is a special signal detected by compatible units (see

Using Auto-Switching Mode

In auto-switching mode, your source

automatically switches from one wavelength to

another. When connected to the light source, a

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.
