Operation - X-Rite SpectraLight III Operation Manual

Note: When powering off the SpectraLight III using the Main Power Switch, wait at least 5 seconds before you power it
on again. This will enable all of the firmware and hardware to properly shut off. If you attempt power on less than 5
seconds after the power off, the unit may not power up. If this occurs, power off the unit, wait at least 5 seconds, and
then power it on using the Main Power Switch.

Selecting a Light Source
To select a light source for viewing a sample, simply press and release the button on the front panel for the light source.
The source remains on until you select another light source or press the Source Off button on the membrane panel.
Using the Source Off Button
The Source Off Button should be used to turn off a selected lamp. You can think of using this button as putting the unit in
"idle" until another lamp source is selected. Do not use the Source Off Button to power off the entire unit. You should use
the Main Power Switch (located to the left of the Membrane Panel) to completely cut power to the unit for maintenance
purposes.
Programming the SpectraLight III
The SpectraLight III can be programmed to power a sequence of light sources, each for a specified period of time. The
program is helpful if you want to view a sample under several light sources in succession and focus on the sample's
appearance rather than operating the front panel.
To set up the program, proceed as follows:
1. Press and hold the Set/Save button until PGM: appears in the front panel display.
2. Press and hold the light source button for the first source in the sequence. Hold the button for the number of
seconds the source should be powered in the sequence and then release.
3. Seconds= ## appears in the front panel display. ## indicates the number of seconds the button has been held. For
example, press and hold the Cool White button for three seconds. Seconds=03 appears in the display.
4. PGM: XX appears in the display. XX indicates the light source you selected. For example, PGM: CW indicates that
Cool White Fluorescent is the first source in the sequence.
5. Repeat step 2 for the next light source in the sequence.
