Nah, I don’t usually toss around numbers. I’m not an ‘stat’ guy who goes nuts posting that online.
According to Minolta, the CS-1000A does measure accurately below 1cd/m2, but just not as tight within the spec as the CS-2000…which is why it isn’t published. Even though it can deliver readings below .0029fL like any other meter, to what degree of accuracy I’m not quite sure.
For the sake of anyone’s curiosity, what is somewhat assuring is that the readings are repeatable at those values – I can take a measurement of .0003 five times in a row. The Y-reading does not bounce around. Even the x/y readings at low light don’t bounce around much, by a few ten thousandths, maybe…in the field, the variances probably aren’t that far off the +/-.001 published spec with the luminance range starting at 1cd/m2. Maybe there’s another factor I’m not considering…? So the results may be good for my clients, but might not be good for the lab which is what this piece was designed for anyway. Visually, everything looks correct. I don’t believe I’m interpreting anything incorrectly. I can’t say the same for my i1Pro at those same readings which is known to be limited to about 1fL. It still delivers readings below, but it’s repeatability is terrible and visually it looks wrong.
