0.3 Safety Instructions
This measuring instrument conforms to the 2004/108/EG)
(EN61010) standard and fulfils the requirements of applicable
European and national directives. Appropriate declarations and
documentation are located with the manufacturer. The user must
read these operating instructions in order to guarantee problem-
free instrument operation and operational safety. The measuring
instrument may only be operated under the specified climatic
conditions. These conditions can be found in Section 3.1
"Specifications". In addition, this measuring instrument may only be
operated under the conditions and for the purpose it was designed
for. The operational safety and functionality are no longer
guaranteed if the instrument is modified or converted. Gann Mess-
u. Regeltechnik GmbH assumes no liability for any ensuing
damage. All risks are assumed solely by the user.
The instrument may not be stored or operated in
aggressive atmospheres or atmospheres containing
solvents!
Static electricity - At low humidities static electricity
charges with high voltages may build up, favoured by
external influences (friction during material transport, high
environmental isolation value), which may not only lead to
strong fluctuations in the measured data or negative
values, but also to the destruction of electrical
components in the instrument. Even the instrument
operator may - inadvertently - contribute to the build up of
a static charge by the clothing worn. A considerable
improvement can be achieved by the operator and the
measuring instrument being absolutely still during
measuring, as well as by earthing (contact with conducting
metal, water or heating pipes, etc.).

Frozen wood cannot be measured.
The notes and tables on allowable or common moisture
conditions in practice and general definitions given in
these instructions were taken from the technical literature.
The manufacturer therefore cannot accept any liability for
correctness. The conclusions drawn from the
measurement results depend on each user's individual
requirements and practical, professional empiricism.
Because the measuring instrument adheres to the stricter
emitted interference (EMC) Class B it may be operated in
residential and commercial environments.
The measuring instrument and any accessories used may
only be used for the purpose intended, as described in
these instructions. The instrument and accessories should
be kept away from children!
Do not measure wood or other materials on conductive
surfaces.
Gann Mess- u. Regeltechnik GmbH accepts no liability for damage
caused by non-compliance with the operating instructions or by
violation of a duty to care during transport, storage and handling of
the instrument when operating, even if this duty to care is not
specifically discussed in the operating instructions.

Introduction

Hydromette BL Compact
CAUTION: There is a danger of injury from the measuring
pins if the measuring instrument is carried without the protective
cover or other protective packaging. There is also a danger of injury
due to careless handling of the measuring pins during the
measuring procedure. Before pressing the electrode pins into walls
or ceilings, ensure that no electrical cables, water pipes or other
utilities are present using suitable means.

1 Introduction
1.1 Description
The Hydromette BL Compact is an electronic moisture meter for
various types of wood and soft building and insulating materials
with a 3-line LCD display. The measuring pins are pressed into the
respective medium and allow recording of the moisture content of
sawn timber, chipboard, veneers and wood fibre materials up to a
maximum of 25 mm thick, as well as insulating materials or normal
gypsum and mixed plasters.

can be performed from here.
2. Type selection: The material type can be selected here.
3. Maximum value: The largest measured value is
displayed
4. Minimum value: The smallest measured value is
displayed.
2.3.1 Measuring Menu (main menu)
The last measured value is shown together with the comment
"Hold". The instrument temperature and the current type are also
shown on the display.
A new measurement can be started in this menu by pressing the
"M" key.
The "Hold" icon disappears from the display during the
measurement and the % sign flashes. If the measured value
remains stable the % sign stays on and the measured value is
stored after releasing the "M" key. The "Hold" icon is displayed
again.
If the new measured value is greater or smaller than the previous
maximum or minimum, "Max" or "Min" flash on the display. The "M"
key is pressed briefly to store the new value as the new minimum
or maximum. A new measurement can be started without altering
the previous minimum or maximum by pressing "M" longer if the
value is not to be stored.
If a measurement is outside of the measuring range (< 6%, > 25%)
a flashing value, which is additionally marked by "LO" or "HI",
warns of this.

2.3.2 Material Settings
The specified material ID is
displayed with the icon for wood
moisture or material moisture.
Material icon and ID
To change the preset for the type, the device must be switched on
and be in the main measurement mode (default after switching on
the device). After pressing the “Down” key the view as shown in
Figure 2-3 appears on the device. Press the “M” key (measure
keY9 briefly to change the preset for the material.
The type ID flashes and can be set using the "Up" and "Down"
keys. Press the "M" key again briefly to save the change.
The type table can be found in the Annex.

Maximum Value
The largest measured moisture
value of a series is displayed
together with the display icon
"Max."
Type icon and ID
To delete a maximum value the displayed value must be selected
by briefly pressing the "M" key (measure key):
The value and the % sign are now flashing and the value can be
deleted by pressing the "M" key longer. Once the value has been
deleted only the % sign flashes. By briefly pressing the "M" key
once again the deletion is confirmed and the % sign disappears.
The instrument returns to the ready mode.
A new measurement can then be carried out using the "M" key.

2.4 Additional Functions
2.4.1 Automatic Shut-down
If no key is pressed for approx. 30 seconds the instrument switches
off automatically. The current data are retained and are displayed
again after switching on.
2.4.2 Battery Monitoring
If the battery icon appears in the display the battery is empty
and must be replaced.
