It will be required to see the xyY readings than the dE reporting because if both devices have 1 dE lets say, the one can have 1dE towards to green and the other 1dE towards to red, so looking only the dE which can be the same for both, doesn't mean that it's ok for sure.
Thanks Ted! Ok, so I should check the xyY readings.
What I'm struggling with is could be meter repeatability and display stability. But also, as well as those two, I don't understand why the target values, are also changing?
I will attach two screenshots, "History 4" and "History 5" tabs are from two sets of readings, one done after the other. I did not change anything, I just did another "read series".
Are [x: CIE31, y: CIE31, Y] representations in the 3d colour volume of the colour that the meter has just read? (hope that's a "yes"!)
Is "Target Y" a representation of the luminance which it thinks it should be getting, if the display is correct? With dE then being calculated from "Y vs Target Y"?
Why are the "Target Y" values different
between the two screenshots? That's really troubling me!
Does anyone have a screenshot or list of the "correct" targetY values from 0-100% in 10step intervals? That would really help I think!
