EVALUATION OF RESULTS
The measuring results are for orientation and pre-evaluation only; it
is not a qualified dampness measurement or relevant to specialist
regulations.
The raw density of the material being measured has a noticeable
influence. Basically, the value displayed with dry and damp building
materials increases correspondingly with increasing raw density.
If the surface to be measured is dirty this will have an influence on
the measuring result. Please remove any dirt from the surface.
Do not take measurements on metallic linings! In corners or
recessed areas a distance of ca.8-10 cm form the edge/recess
must be maintained.
If the measured surface is of rough structure measured values will
be higher.
Measured values can be taken from 20 mm up to 40 mm depth.
Underlying layers cannot be measured.
If the material measured has a thickness of less than 20 mm other
material layers can influence the measured value.
