0.3 General Notes
This measuring device fulfils the requirements of the applicable
European and national directives (2004/108/EC) and standards
(EN61010). Appropriate declarations and documentation are held
by the manufacturer. To ensure trouble-free operation of the
measuringdeviceandoperationalreliability,the usermustcarefully
readthe operatinginstructions.Themeasuring device mayonlybe
operatedunderthe climaticconditions specified. These conditions
can be found in Chapter 3.1 "Technical data". This measuring
device maylikewise onlybe used under the conditions and for the
purposes it was designed for. Operational reliability and
functionality are no longer ensured if the device is modified or
adapted. Gann Mess- u. Regeltechnik GmbH is not liable for any
damagearisingfrom suchmodificationsor adaptations. The risk is
borne bythe user alone.
The device must not be stored or operated in aggressive
air or air containing solvents!
Static charge - at low levels of air humidity aided by
external factors (friction during material transport, high
insulation of the surrounding area), static electricity can
build up with high voltages, which can not only lead to
strong swings in measured values or minus values, but
also to the destruction of electrical components in the
device. The operator of the measuring device can also,
unintentionally, contribute to the build-up of static charge
from his/her clothing. A significant improvement can be
achieved by ensuring the operator and the measuring
device remain completely still during the measurement
process and by grounding (touching conducting metal,
water or heating pipes, etc.).
Frozen wood cannot be measured.

The notes andtables intheseinstructions on permitted or
normal humidity conditions in practice and the general
definitions of terms have been taken from the specialist
literature. No responsibility can therefore be taken bythe
manufacturer for the correctness of this information. The
conclusions to be drawn from the measurement results
are relatedto the individualconditions and the knowledge
drawn from professional experience for each user.
The measuringdevicemaybe operated in residential and
commercial areas, as the stricter class B for emitted
interference (EMC) has been adhered to.
The measuring device and anyaccessories mayonlybe
properlyusedas describedintheseinstructions.Keep the
device and accessories out of the reach of children!
Wood and other materials should not be measured on
conductive surfaces.
Gann Mess-u. RegeltechnikGmbHaccepts no liability for damage
resultingfrom non-adherencetothe operatinginstructionsor bynot
taking proper care during transport, storage and handling of the
device during operation, even if this requirement for care is not
specificallyaddressed in the operating instructions.

0.4 SafetyAdvice
WARNING: There is a riskof injuryfrom the measurement
probes of the electrodes. Before inserting the electrode pins into
wooden panels or similar, use suitable methods to ensure that
there are no electrical wires, water pipes or other supply lines at
this point.
1 Introduction
1.1 Description
The Hydromette BL H 40 / HT 70 is an electronic wood moisture
measuring device for precise measurement of sawn timber (up to
180 mm thick), chipboard and veneers with a high-quality
measurement amplifier and 3-line LCD display.
The device has a wood type switch to automatically correct
measurement values for over 300 types of wood, and there is also
a wood temperature compensation. The HT 70 also offers a
connectionfor various temperaturemeasuring devices. In addition,
5 customer-specificwoodcharacteristiccurves canbeprogrammed
(only2 characteristic curves are available in the H 40).
The electrode is inserted into the respective material to be
measuredandallows themeasurementofmoistureinsawntimber,
chipboard, veneers and wood fibre materials up to 180 mm thick
(with electrode M18).
