3.8.6 Calibration Validity
White and black calibration as a standard for chromatic data, is required
to be done correctly,otherwise it will affect the validity of the data.
When the calibration environment is very different from the test
environment of the current sample(for example temperature fluctuate
violently),the instrument is required to be re-calibrated timely. It is also
recommended to re-calibrate if the calibration time is more than 24 hours
from last successful calibration.
In the system menu, click “Calibration Validity” to select as shown in
