6.11 Measuring material moisture
6.11.1 Resistance measuring principle
Be sure neither supply lines (electric lines, water pipes, etc) nor a
metal subsurface is present at the location to be measured. Insert
the electrodes as far into the material as possible but never use
excessive or sudden impact force as this could damage the device.
Always pull the device out of the material with left/right twisting
motion. Perform several comparative measurements at different
GB
locations to minimise measurement error. The sharply pointed
electrodes present an injury hazard. Always put the safety cap on
the device when it is not in use or being transported.
Wood
The location to be measured
should be untreated, free of knots,
dirt and resin. Measurements
should not be made on the end
faces of wood because these areas
dry particularly quickly such that
they produce incorrect measure-
ment results. Perform multiple
comparative measurements. Wait
until the % symbol stops blinking
and remains constantly lighted.
Only then are measurement values
stable.
Mineral building materials
Be aware that walls (or surfaces)
with differing material structures,
or even variations in material com-
position, can cause measurement
results to be falsifi ed. Perform
multiple comparative measure-
ments. Wait until the % symbol
stops blinking and remains
constantly lighted. Only then are
measurement values stable.
