Colorimetrics

Tristimulus X, Y, Z, x, y (3100 and 3300 models)
These values can be computed with any of the supported
illuminants and observers. When tristimulus data is specified to be
used for a task, you enter the illuminants/observer combination at
that time. A single measurement is required for tristimulus output.
Reflectance Data (3300 model)
Reflectance data output is supported either digitally or graphically.
NOTE: Both models will support the output of just the samples
reflectance data, or the difference between the sample and a
standard.
CIE LabCh Data (3300 model)
Several kinds of tasks are supported to produce the exact data
desired.
CIE Lab and Lch data for the sample and standard can be output, or
just the difference between the two. In addition, the difference can
be accompanied by verbal descriptors.
Hunter Lab Data (3300 model)
Several kinds of tasks are supported to produce the exact data
desired.
Hunter Lab data for the sample and standard can be output, or just
the difference between the two. In addition, the Hunter Lab task
computation supports all illuminants supported by the instrument.
