8. Measurement of area and recognition
There is no order in the measurement of the areas. The measured area will be
allocated automatically to the reference value with the least color distance.
In case a patch is not recognized it will be marked by a question mark. We
recommend you to measure the area again. Please be sure to measure in the
middle of the area since this method results in the best accordance with the
provided reference.
If the area is still not recognized after the second measurement, you can force the
software to adopt the measurement value by selecting the area with the mouse
and transacting a measurement.
The area will be showed with a question mark and a check mark.
We highly recommend you to transact the measurement by standing, since it’s
better for a more specific positioning.
The tolerance for the identification of an area is a color distance of dE3.
Only three areas are allowed to have a dE over 3. One measurement value on
the chart may have a value of dE 5. If this value is exceeded it will not be possible
to profile the device.
