• The greatest measurement accuracy lies in a range between
6 and approx. 28 % wood moisture content. The
measurement results become less accurate above 28 % since
the resistance changes only slightly with the moisture.
Meaningful measurements are practically impossible below 6
% wood moisture content, because the result is influenced by
molecular attraction forces.
• The moisture measurement becomes less accurate above the
fibre saturation point.
• The temperature value set in the device must be identical with
the temperature of the wood. If the set value were 20 °C and
the temperature of the wood 30 °C for example, the
B - 25
measurement result error would be approx. + 1.5 % if the
temperature compensation were not to be taken into account.
• The accuracy of the measurement is dependent on the
application pressure of the measuring spikes. The measuring
spikes must contact the wood so well that the transition
resistance is small compared to the measured resistance.
• In order to check the sample measurements, the values
determined should be confirmed by means of random
comparison Darr samples.
