As far as I know, the instrument is capable of measuring below 48 and 11.9
cd/m2. But this is my impression ;-)
I could ask Minolta. But since I routinely take measurements down to 1 cd
and less on my monitors, I doubt that the instrument is not capable of
taking readings below 48 and 11.9.

So true.

Ah! Good question. To which I don't have the answer :(
