Selection of the right calibration curve:
Below you can find advices for selecting the right curve. If you are
not sure about the right calibration curve, we recommend to carry
out a comparison measurement by kiln drying (EN 14774) once.
 Woodchips: standard chips of wood (forest wood chips)
according to EN ISO 17225-1 class P16, P31 and P45.
 Coarse WC: for coarse chips of wood P31 & P45 but with fewer
fines. If the weight of the filled 13 litre bucket is under 2,6 kg, the
wood chips calibration curves (2,4k resp. 2,0k) have to be used!
