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).
