Out the other day checking my stacks after all the rain this year. Pulled a few 2 year old splits and got a center reading of 24-30. Edges were at 15-18. This wood felt and sounded dry. Measured some very dry pine and found the same center high reading. Meter must be off and it sure was. Changed the batteries and those same 24-30 splits now were 14-16. BTW batteries checked good and I re-split the wood before checking.
