PRELIMINARY OPERATING INSTRUCTIONS
This color analyzer measures luminance (in ft-Lamberts or candelas per square
meter), chromaticity, (CIE 1931 x,y values) and correlated color temperature,
cct, in Kelvin. It has an optical viewfinder with a seven degree field of view.
Measurements are made within a one degree area that is indicated by a small
circle in the center of the field. The measurement results are displayed within
a window on your laptop computer. The software included is designed to work
with Windows versions 98, ME, 2000 and XP.
GETTING STARTED
You should have: the Projection Color Analyzer, a USB cable and the software
installation CD.
IMPORTANT
Install the Color Analyzer software BEFORE plugging in the cable and
analyzer.
Insert the CD in the computer CD tray. The install software should automatically
start. If not, go to the “Run” item on your start menu and enter X:\set up.
(Where X is the letter indicating your CD drive.) Follow the instructions. After
the sofrtware installation is complete, connect the Color Analyzer to the USB
port of your laptop computer using the cable supplied. Next, find the little
rainbow icon on your desk top.
Double click on this, the Color Analyzer icon, to start the software.
If you point the analyzer at a wall or surface in the room, the laptop display
will indicate the luminance and color characteristics of the light reflected from
the surface.
The Color Analyzer display window, (figure one), shows the luminance,
chromaticity and the correlated color temperature values on the left and a
graphical display of the color characteristics on the right. The position of the
small spot within the color chart shows a representation of the target color
measured within the viewfinder’s one-degree circle. The x and y values of
chromaticity are shown on the horizontal and vertical scales respectively.
