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 falsified. Perform multiple
comparative measurements.
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.

Bar graph display
The display can be toggled between
measured values and a bar graph by
pressing the arrow buttons. The bar
moves from left to right as the moisture
level increases. The maximum value is
also calculated. The arrow buttons can
be used to switch back to the measured
value display at any time.

MAX value
The greatest measured value is shown in the bar graph display while
taking a measurement. The value is automatically reset before starting
a new measurement.
