Thanks Graeme! Just tried it, and it's worked. I wouldn't suppose that
it would measure color temperature for 40$ I've bought it :) Have tried
to measure ambient light previously using menu option in dispcal, but it
failed(I did it long ago and not on version 1.0.4) so I stop checking
this menu at all.

Can you please advice what would be best placement of Huey in space
during light measuring? I know that it's recommenced to place meter
"beside the display and point upward", but I'm not sure where should it
be exactly. Should I place it between me and monitor on my eye level or
on the table? As difference in reading for these two levels are 70 lux
