Note:
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 there is any metal in substructure (constructional steel, channels, pipes, pla-
ster rails, etc.) and with normal coverings, the display jumps to ca. 50 digits
for otherwise dry surroundings.
It is only possible to reach a conclusion about the absolute dampness in wt-%
or the dampness in CM-% if the normal drying out process has taken place
(e.g not during or shortly after the use of drying agents or heat guns). If there
is not a roughly normal variation in dampness between the surface
and the interior, too low a measured value may be indicated.
The raw density of the material being measured has a noticeable affect.
Basically, the value displayed with dry and damp building materials increases
correspondingly with increasing raw density.
The values given in the table below are indicative and non-binding.
Please bear in mind, when evaluating the measured value displayed on the
NON-Contact Moisture Meter with respect to the material, that it is not a
dampness measurement qualified to VOB or the relevant specialsit
regulations.
All information and tables in these operating instructions concerning permis-
sible or common dampness conditions in practice as well as the general defi-
nition of terms are taken from the technical literature. The manufacturer of
the instrument can thus not give any guarantee for the correctness of this
information.
The conclusions to be drawn from the result of measurements by each user
depend upon the individual circumstances and his experience gained from
professional practice.
