– Make sure that the sensor pads make good contact with the material with
no air inclusions.
– The contact pressure compensates for unevenness of the surface and small
dust particles.
– Measured surface should be free of dust and dirt
– Always take spot measurements while exerting a contact pressure of 2.5 kg.
– For quick checks, while exerting light pressure, you can slide the device over
the surface. (Look out for nails and pointed objects! Danger of injury and
damage to sensor pads!) Measure again at the highest deflection point while
applying 2.5 kg contact pressure.
– Keep at least a 5 cm distance from metal objects
– Metal pipes, electric lines and reinforcing steel can falsify measurement results
– Always measure at several different spots
The operating principle of the device can only determine the material moisture
measurement in % and show the moisture content on the LED display when
the material matches the specified internal material characteristics.
Plaster with wallpaper: Wallpaper affects the measurement to such an
extent that the displayed value is falsified. Nevertheless, the reading can still
be used to compare the measurement at this spot with the measurement at
another spot. The same is true of tiles, linoleum, vinyl and wood used to cover
building materials.
In some cases the measuring device can measure through these materials
as long as they contain no metal. The reading should however be taken as
a relative measured value.
Plaster: Plaster mode is configured for a plaster thickness of 10 mm applied
on concrete, lime-sand brick, cellular concrete.
