Measurement Preparations
Setting the Wood Group
For optimum measuring results, the wood group must be set before each measurement.
Select the appropriate wood group with the button (2). The selected wood group is
shown in the display (3).
Tip: If the wood you are using does not appear in either of the two wood groups or you
are unsure which type of wood is closest to the wood you are using, use wood group A.
This generally indicates a higher value. This ensures that you are not processing your
wood too early or too moist.
When switching off the measuring tool, the set wood group is saved. When the measur-
ing tool is switched on again, the last selected wood group is preset in the measuring
tool.
Object to be Measured
The area in the wood to be measured must be untreated and free of branches, dirt, resin,
rot, knurls or other defects. The wood should be free of chemical surface treatment.
Do not perform any measurements on end surfaces, since the wood here dries out par-
ticularly quickly. This could lead to incorrect measurement results.
For measuring the humidity of fuels, it is advisable to split up the wood sample before
measuring and then take measurements at three different points. Measuring points:
5 cm from the left and right cut edges respectively, and in the centre of the piece of
wood (see figure B).

Measuring process

Take off the protective cap (6). To do this, lightly pull on both sides of the protective cap
(6). Attach the protective cap to the rear of the measuring tool (magnetic), see figure on
page 3.
Before taking the measurement, ensure that the ambient temperature corresponds to
the temperature of the object to be measured. If required, wait until the measuring tool
has acclimatised to the ambient temperature.
Carry out the moisture measurements at least 5 cm from the cut edges, since the wood
on the edge dries out quicker than in the centre (see figure B).
Do not measure the surface of the wood. Water that may have accumulated here as a res-
ult of rain or dew can affect the measurement.
Always measure across the grain. Do not measure parallel to the grain or along the
growth rings (see figure A).
The measurement is taken at the depth at which the pins (5) are inserted. Optimum
measuring results are achieved when the pins are inserted approx. 4–5 mm into the
