02. Purpose of use

This instrument provides an approximate determination of the material
or wood moisture content applying the resistance method. Areas of
use include the recording of wood moisture levels in cut timber and
firewood. In addition the instrument can be used to record moisture
in soft building materials such as cement or plaster. The resistance
method is an indirect method of measurement enabling conclusions
to be drawn from the material's electrical conductivity concerning
its moisture content. Variables that are able to alter conductivity, for
example electrically conducting materials or dissolved salts, can
thus have an immediate effect on the measured data determined.
For this reason the measured values displayed are only to be seen
as an indication of the moisture content.

Notes for use when measuring wood moisture levels:
For the measurement of wood moisture levels, a calibration curve
is stored in the instrument, which corresponds to the average of
relevant types of wood in Europe at a wood temperature of 20°C. No
further adjustments are therefore necessary for a rapid and appro-
ximate determination of the wood moisture content. If exact wood
moisture levels at other wood temperatures, or taking into conside-
ration the type and green density of a particular type of wood, are
required, we recommend an additional control measurement apply-
ing the kiln dry ing method, or use of a wood moisture measurement
device with a temperature compensation function and the option to
select a specific calibration for the type of wood in question.
Notes for use when measuring material moisture levels:
For the rapid determination of material moisture no further adjust-
ments to the instrument are required. In the assessment of the mea-
