Performing calibration
Zero calibration and white calibration is effective only while the Spectrophotometer
remains switched on. If it is switched off and then switched on again, both zero calibration
and white calibration must be performed before measurements are taken.
c The calibration becomes effective only when being performed under six kinds of measurement conditions.
Therefore, for example, when performing the measurement of SCI and SCE alternately, or performing the
measurement by switching the measurement area in a sequential order, if you perform zero calibration
and white calibration (0% calibration and 100% calibration) in advance as to up to six kinds of necessary
measurement conditions, you do not have to perform calibration every time the measurement conditions
are changed. However, to more accurately perform measurement, it is recommended to perform zero
calibration and white calibration every time measurement conditions are changed.
c When the calibration has been performed under the seventh kind of measurement conditions, the oldest
calibration becomes ineffective and the calibration performed under the seventh kind of measurement
conditions becomes effective as the latest. Moreover, when the calibration is re-performed under
the same measurement conditions as one calibration that was already performed, not that the oldest
calibration becomes ineffective, but the calibration already performed under the same measurement
conditions becomes ineffective and the re-performed calibration becomes effective as the latest.
{ Due to temperature changes in the surrounding environment and heat generation caused by repeated
applications, the indicated values may subtly deviate, but if the calibration is regularly performed, the
measurement accuracy will improve.
