Preparing for
Measurement
The items x, y, u', v', Δx, Δy, Δu' and Δv' are expressed to four decimal places. Other colorimetric data is
expressed to two decimal places.
The number of decimal places can be changed. See page 43 for details.
The CS-S10w software enhances calculation accuracy by performing internal calculations with num-
bers greater in magnitude than those actually displayed. Consequently, the least significant digit dis-
played may differ from that of the instrument by one digit due to rounding or color space conversion.
*1 Selecting all waveforms of the spectral data will make the display speed slow. It is recommended to
select necessary waveforms only.
*2 When the observer is 10°, Lv is as follows:
- For a tristimulus value, displayed as
“------”.
- For spectral data, calculated from the Y value for 2° observer.
*3 When a user equation is added, the equation can be specified in the following procedure.
