When examining wood, make sure that measurements are carried out in accor-
dance with its
fi bre direc on – otherwise the measured values will be too low.
The measuring direc on is correct when the wood fi bre direc on is parallel to
the indicator (see below).
REFERENCE MEASUREMENT
How to locate moist and leakage:
Set the Material code to 200 or CC2
Hold the spring electrodes or the bo om sensor to a surface you know
is dry
The received value corresponds to a “dry material” and could be used
as reference value
Now it is possible to locate moist and leakage using the reference value
By moving the measurement springs over the surface you could quickly
locate the leakage and
fi nd out about the extent of the moist damage.
