The settings are used globally byother measurement functions. The selected white standard is used fordominant wavelength calculation. The integration time setting can bevaried from 2.5ms to 20s. It is specified in μs. Results from the Herainclude a clip and noise indication which indicate, whether the measuredlight is too bright (clip) or too low (noise). When clipping is detected, theresulting colour will not be correct and a lower integration time should bechosen. When noise is detected, a larger integration time should bechosen, see table 7 on next page. |
