5 Using a Light Source
(FLS-300 and FOT-300)
The FLS-300 may contain up to three sources (one-port models) or up to four
sources (two-port models). The FOT-300 may contain up to three sources.
Activating/Deactivating a Light Source
Only one source may be active at a time. When no source is active, the unit displays
NONE
(FLS-300) or leaves the top left corner empty (FOT-300).
To activate a light source and change the wavelength:
Press
(source)
to activate each available source in turn. The unit displays the
wavelength and modulation.
To deactivate the light source:
Press
(source)
until you get past the last source.
OR
Hold down
(source)
a few seconds.
Modulating the Source Signal
When you activate the first source, the signal is always CW (unmodulated). When
you switch sources, the modulation remains the same. Modulation is indicated in
the top left (port #1) or top right (port #2) corner.
Available modulation values are: CW, Auto, 270 Hz, 1 kHz and 2 kHz.
Note:
Auto is a modulated signal detected by compatible units (see
Automatically Detecting Wavelength
on page 15). It provides longer
battery life than CW, but covers a reduced power range.
To change the signal modulation:
1.
Activate the source.
2.
Press
to switch between available modulations.
