0.2 WEEE directive 2002/96/EC law on electrical
and electronic equipment
Disposal of packaging, the battery and the device must be
undertaken in accordance with the legal requirements at a recycling
centre.

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
measuring device and operational reliability, the user must carefully
read the operating instructions. The measuring device may only be
operated under the climatic conditions specified. These conditions
can be found in section 3.1 "Technical data". This measuring
device may likewise only be 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
damage arising from such modifications or adaptations. The risk is
borne by the 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 earthing (touching conducting metal, water
or heating pipes, etc.).
Frozen wood cannot be measured.

The notes and tables in these instructions 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 by the
manufacturer for the correctness of this information. The
conclusions to be drawn from the measurement results
are related to the individual conditions and the knowledge
drawn from professional experience for each user.
The measuring device may be operated in residential and
commercial areas, as the stricter class B for emitted
interference (EMC) has been adhered to.
The measuring device and any accessories may only be
properly used as described in these instructions. 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. Regeltechnik GmbH accepts no liability for damage
resulting from non-adherence to the operating instructions or by not
taking proper care during transport, storage and handling of the
device during operation, even if this requirement for care is not
specifically addressed in the operating instructions.
0.4 Safety advice
WARNING: There is a risk of injury from 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 41 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 as well as wood
temperature compensation.
The M20 electrode is inserted into the respective material to be
measured and allows the measurement of moisture in sawn timber,
chipboard, veneers and wood fibre materials up to 180 mm thick
(with electrode M 18).
