Graeme,

the device is still under warranty. I'll see what XRite says about it.

Thanks,

Karl.

I would suspect then that your instrument is broken then. Even if
the white point is a bit different (and this can be the case
depending on the construction of the light bulb, voltage etc.)
I would expect it to be close to the Planckian locus, and
32 delta E is 10 times bigger than the 3 that I got.
(The Z or blue channel seems to be a bit too high).
