Wood with a relative material moisture level greater than 20%
!
should not be used for burning. The optimum calorific value
of wood is achieved at a level of <15%.
Mineral building materials
Be aware that walls (or surfaces) made
of several different materials, or even
variations in the material's consistency,
can cause measurement results to be
falsified. Perform multiple comparative
measurements.
Building moisture measuring range
< 0,2%
≥ 0,2% to < 0,7%
≥ 0,7% to < 0,9%
≥ 0,9%
The integrated building material characteristic is adapted to
gypsum plaster. The measuring ranges for building materials
!
differ significantly and also vary between manufacturers.
The integrated characteristics does therefore not apply to all
possible building materials. If necessary, check values using
other measuring methods such as the Darr method.
Tip: Moisture measuring devices that operate in accordance with
the resistance method can be used to compare measuring points –
in this case the numerical value only serves as an index value.
Take a sample measurement in a dry area of the same material,
note down the value and compare against values of the areas to
be measured. Higher values indicate more moisture. In this way it
is possible to detect moisture paths in the material irrespective of
the material or material combinations (e.g. plaster with wallpaper).

Temperature measurement
To measure the ambient temperature switch the device to °C or °F.
!
The sensor may take longer to settle under conditions where
temperatures fluctuate considerably.
Information on maintenance and care
Clean all components with a damp cloth and do not use cleaning
agents, scouring agents and solvents. Remove the battery(ies) before
storing for longer periods. Store the device in a clean and dry place.
