Resistance measurement / material moisture measurement
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 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.
Mineral building materials
Be aware that walls (or surfaces) with differing material
structures, or even variations in material composition, can
cause measurement results to be falsi ed. Perform multiple
comparative measurements. Wait until the % symbol
stops blinking and remains constantly lighted. Only then
are measurement values stable.
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 measurement results. Perform
multiple comparative measurements. Wait until the %
symbol stops blinking and remains constantly lighted. Only
then are measurement values stable.

Capacitive measurement / material selection
Two different wood groups and material-
independent index mode can be selected
in capacitive measuring mode. Measurements
carried out in index mode are not material-
related, i.e. for materials, for which no
characteristics are stored in the device. Select
the required material by pressing the „SET"
button. The wood groups that can be selected
are listed under 11 in the following table.
