The test is to measure light that falls in the overlap range on both ranges.
My experience - even with really good meters like Luna Pros - is that they do
NOT match across ranges when the value is at the extreme end of the low range.
These meters are most accurate when they are around mid-deflection of the
needle.
They are highly nonlinear at the ends.
I say this having just completed cleaning, overhauling, adjusting, etc. a
couple of Luna Pros and a Luna Six.
