I've never had a way of checking its accuracy, but by comparing the
reading of the air dried stock to that of kiln dried stock of the same
species I've never had a problem.


You always have a way of checking its accuracy. 150 degree oven until the
measured piece ceases to lose moisture (by weight) and compute. That's how
they developed those corrections you refer to for different species.
