Material icon and ID
A measuring process is started by pressing the "M" key.
The type ID 0 stands for measurement in “digits”. The scale then
ranges from 0 to 199.9, and the percent sign and material icon
disappear. This value indication allows quick scanning of large
areas for maximum moisture of the extent of moisture damage.
Digital values are dimensionless measurement values and not
real moisture values as a percentage!
Measure by pressing the “M” key and placing the ball electrode on
the material to be measured.

2.2 Settings Menus
By repeatedly pressing the "Up" and "Down" keys the following
menus can be selected in sequence (sequence using the "Down"
key; the menus are accessed in the opposite direction using the
"Up" key):
1. Measuring menu (main menu): The measuring process
can be performed from here.
2. Type selection: The material type can be selected here.
3. Alarm value setting: This allows the user to set a
measurement value threshold that will trigger an acoustic
signal when exceeded; the set limit will be displayed in the
second line.
4. Maximum value: The largest measured value is
displayed.
2.2.1 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. After the “M” key is released, the measured value is
stored. The "Hold" icon is displayed again.
If the new measured value is greater than the previous maximum,
"Max" flashes on the display. The "M" key is pressed briefly to store
the new value. A new measurement can be started without altering
the previous maximum by pressing "M" longer if the value is not to
be stored.

Basic Functions

Hydromette BL Compact B 2
If the alarm function is turned on, a warning signal sounds when the
adjustable alarm value has been exceeded, and the measurement
value flashes. At the same time, the selected alarm value is shown
in the second line of the display.
2.2.2 Material Settings
The specified material ID is
displayed with the icon for material
moisture.
Material icon and ID
To change the preset for the material, 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 display. Press the "M" key (measure
key) briefly to change the preset for the material.
The material ID flashes and can be set using the "Up" and "Down"
keys. Press the "M" key again briefly to save the change.
The material table can be found in the Annex.

2.2.3 Alarm Value Setting
The alarm can be activated or
deactivated from this menu. The
alarm value can also be set.
Material icon and ID
If no maximum value is stored, or if it is deleted, the “OFF” icon
appears.
To enter a new maximum value or to activate the function, briefly
press the “M” key. The display begins to flash. Pressing longer on
the “M” key activates the alarm value. The alarm value for each
material ID set in measuring mode can be entered separately by
using the “Up” and “Down” keys. After the desired value has been
set, or a previously available one (re)activated, press briefly on the
“M” key to confirm the entry. The instrument will return to standby
mode.
If 0 is chosen as the material ID, the display will show in digits,
without percentage data.

4 Notes on Use
4.1 General Notes
The Hydromette BL Compact B 2 is a dielectric moisture meter for
determining the moisture and moisture distribution in building
materials, such as masonry, concrete, screed, etc.
Measurement is based on the measurement principle of the
capacitive electrical field. The measurement field forms between
the active ball at the upper part of the instrument and the substrate
mass to be measured. The change in the electrical field by the
material and moisture is registered and digitally displayed (as digits
or weight percentage).
The measurement is a relative one, which means that the
difference between the dry and moist building material is shown.
An inference as to the absolute moisture by percentage of weight
or by moisture per CM percentage is possible only during the
normal course of drying.
One influencing factor to be considered is the raw density of the
building material to be tested. In general, for dry and moist building
materials, as the raw density increases, the displayed value rises
correspondingly (see also Chapter 4.4, page 23).

Notes on Use
20
Hydromette BL Compact B 2
4.2 Orientation Values
The following data serve as a an orientation guide for anticipated
display values:
Residential spaces
dry 20 - 40 digits
moist 80 - 140 digits
Cellars (old buildings)
dry 40 - 60 digits
moist 100 - 150 digits
Depending on raw density, readings over 130 digits indicate that
condensation is beginning.
Depending on the height of the covering, metal in the subsurface
(iron reinforcements, wires, pipes, stucco bars, etc.) can raise the
measurement value. This should be considered when evaluating
the displayed values in relation to the covering.
