   Characteristic curves  

15 characteristic curves for wood  
additionally reference curve (rEF) for high-resolution relative  

   Resolution 

 0.1 %; for more than 19.9 %: 1 % (for both %u and %w) 

   Moisture rating 

Display: Rating of the moisture in 6 levels from WET to DRY 
Acoustic: Signal tone, depending on moisture rating 

   Accuracy
