Programming a Sequence
Detecting "Metamerism"
Connecting the byko-spectra to a Power Supply
Turn off all sources using OFF (G) button. UV (B)
is independently controlled and can be used with
another source or by itself. If the Home Light (E) is
selected and not switched for 15-20 minutes then
the unit will turn all lamps off (this is a lamp and
energy saving feature).
Press and hold the yellow SEQ (A) button. While
holding the SEQ button, press the buttons for the
sources you wish to turn on in the order you want
them activated (up to 10). After selecting your light
sources, while still holding the SEQ button, press
the OFF (G) button for the length of time you want
each source to be on (note: all sources will be
turned on for the same time period - if you want an
individual light source to be on 2 or 3 times longer,
simply press its button two or three times while
programming the sequence. The sequencing "On"
period has been programmed to not allow "On"
times to be less than 5 seconds). After releasing
the OFF button, you can release the SEQ button.
To use the automatic sequence simply press the
illuminated yellow SEQ button. The sequence will
remain in memory until a new program is entered,
or, if you press the SEQ button and hold while
pressing the OFF button, this will also clear the
sequence. You can use the selection buttons to
use the unit normally even though a sequence is
stored.
When two color samples match under one light
source, but not under one or more other light
sources, the "color-match" is metameric. This
means that the colorant formulation in one sample
differs from the formulation in the other, resulting
in differing spectral reflectance factor curve
shapes. A metameric color match can also be
referred to as a "conditional" color match, since
