Mineral building materials
Be aware that walls (or sur-
faces) made of several dierent
materials, or even variations in
the material‘s consistency, can
cause measurement results to
be falsied. Perform multiple
comparative measurements.
Read measurement results
from the right-hand building
materials scale.
Refer to the conversion table
below in order to obtain more
precise measurements for
dierent materials.
5Wood
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 becausethese areas
dry particularly quickly such
that they produce incorrect
measurement results.
Read measurement results
from theleft-hand wood
moisture scale.
Refer to the conversion table
below in order to obtain more
precise measurements for
dierent materials.
Function/application:This material moisture instrument detects
and evaluates the material moisture content of wood and building
materials by way of electric resistance measurement. The displayed
valueis material moisture in % with respect to dry mass. Example :
100% material moisture for 1 lb of wet wood =.5 lb water.
Measurement procedure notice:
Be sure neither supply lines (electric lines, water pipes, etc) nor a
metal subsurfaceis present at the location tobe measured. Insert
the electrodes as far into the material as possible but never use
excessive or sudden impact force as this could damage the unit.
Always pull the unit out of the material with left/right twisting
motion. Perform several comparative measurements atdie-
rent locations to minimise measurement error.
The sharply pointed electrodes present an injury hazard .Always
put thesafety cap on the unit when it is not in use or being
transported.

Table notices:
Measurements indicated on the instrument‘sdual-scale are based
on the common built-in material characteristics for wood and
building materials.More precise results can be obtained forthe
given wood or building material when the indicated measurement
is referenced to the conversion table.
Example: Measurement on the left scale: 24%, corresponds
to 1,2%for gypsum plaster. Values with a grey background are
considered to be wet.

General notices:
Functional and operational safety is only warranted when the
instrumentis operated within thespecied climatic conditions
andis only used for those purposes for which it is designed.
Responsibility fortheinterpretation of measurement results and
consequentactions taken lie entirely with theuser.
Warranty
The warranty period is 1year from thedate of purchase. The warranty
covers all material ormanufacturing defects occurring duringthis time.
The following are excluded from warranty: Damage due to improper
use (e.g. operationwith wrong type of current/voltage, connection
to unsuitable powersource,fall onto hardsurface, etc.) or improper
storage, normal wear and tear, and defects which only insignicantly
impair the value or suitability for use. Any tampering by unauthorised
persons will render this warranty void. In the eventthat you need
to claimwarranty, please takethe complete devicetogether with
all information andthe invoiceto one of ourdealers and have them
contact us.
