5 Using a Light Source
(ELS-50)
The ELS-50 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

Press to activate each available source in turn. The unit displays the wavelength
and modulation.
To deactivate the light source:
Press until you get past the last source.
OR
Hold down

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 corner.
Available modulation values are: CW, 270 Hz, 1 kHz and 2 kHz.
To change the signal modulation:
1. Activate the source.
2. Press
to switch between available modulations.
Note:
When the output signal is modulated
(270Hz, 1kHz, 2kHz), you will notice the
mention out blinking in the top left corner of the display.
