Ok I just picked one up and I am not sure I'm reading it correctly. It seems simple enough but I find that I can change the reading dramatically based on how hard I press it into the wood. If I press very firmly into a newly split piece of wood I can see the reading go from 20% to as much as 35% with heavy pressure.
So what is the correct method, just contact or very firm pressure?
