Wood: As the wood temperature influences
conduction, the correct wood temperature
must be set. There is a choice of two
temperature corrections.
2.1.3 Accuracy
FMC, FMD, FME, FMW-B / FMW-T
The material to be measured and the number of measurements determine the final
accuracy of the moisture measurement. The reasons for this include the inhomogeneous
composition and the moisture distribution.
As a rule, the greatest accuracy is obtained when a number of measurements are taken.
2.1.4 Measuring depth
FMC, FMD, FME, FMW-B / FMW-T
Material that has been artificially dried, will have a higher moisture content at the core than
at the edge.
Wood: The moisture content of a piece of wood is determined at about 1/3 of the thickness
of the wood. The reference values are also based on this. If the moisture content of the
core of a thick piece of wood must be determined, the wood can be sawn in two in order to
measure the core more easily.
2.1.5 Measuring methods
FMC, FMD, FME
Using
insulated
measuring
moisture content is measured between the
non insulated points of the measuring pins.
The moisture content along the whole
length of the measuring pin is measured
using the non insulated measuring pins. It is
typical that the highest moisture content is
always
measured
between
insulated parts of the measuring pins.
2.1.6 Measuring direction
FMC, FMD, FME
In general, it is of no consequence whether
the measuring pins are placed lengthwise or
crosswise. Wood: Preferably crosswise to
the grain.

The sensor measures the average moisture
content to a depth of 25 mm. Wood: For
wood with a thickness of less than 10 mm,
several sections can be laid on top of one
another. As it is possible to measure
through the material, notice should be taken
of what is behind the wood.
