Notes concerning displayed values:
The CS-S10w software enhances calculation accuracy by performing internal
calculations with numbers greater in magnitude than those actually displayed.
Consequently, the least significant digit displayed may differ from that of the
instrument by one digit due to rounding or color space conversion.
Because the tolerance judgement calculation and graph-plotted points are also
processed with numbers greater in magnitude than those actually displayed, the
judgement result or plotted points may differ from those obtained with the val-
ues displayed on the instrument.
Each colorimetric value of the data measured with a spectroradiometer or
obtained by manual input of spectral data is calculated from spectral data. Each
colorimetric value of the data measured with a chroma meter or obtained by
manual input of colorimetric data is calculated from XYZ data. As a result, the
colorimetric value of the average value obtained by the manual averaging mea-
surement or by the averaging of list data may differ from the average of colori-
metric values displayed in the list.
