value,click "L" to input L value as shown in Figure 32, input the
corresponding L value and confirm. Input all standard values and click
to confirm,the input standard will be stored in the standard record list,and
the standard index will be cumulative.
Note:In the instrument, users can’t manually input the reflectance and the
input standard data is only valid in the current observe angle,
measurement mode and light source. In the check standard record
interface,if the observer angle, measurement mode and the light source
changed,the corresponding chromatic data will be displayed as "- - - - -".

3.2Calibration
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.
