material moisture measuring device controlled via smartphone BM31WP
Carrying out a measurement
Put the sensor at a right angle completely on the material to be
measured and observe a minimum distance of 8 to 10cm to
corners.
Info
Please note that the displayed values are merely rough
reference values which cannot replace mandatory
CMmeasurements. Since, particularly in case of
mineral building materials, the measurement results
can be influenced by salinization as well as chemical
additives, the determined values shall only be used as
an indicator of near-surface material moisture, not for
an absolute assessment.
Info
Note that moving from a cold area to a warm area can
lead to condensation forming on the device's circuit
board. This physical and unavoidable effect can falsify
the measurement. In this case, the app will either
display incorrect measured values or none at all. Wait a
few minutes until the device has become adjusted to
the changed conditions before carrying out a
measurement.
Individual value measurement
When the appSensor has been successfully connected to the
terminal device, an individual value measurement is started and
the first determined value will be indicated.

Measuring principle
The measuring device at hand serves for the rough
determination of the material or wood moisture content
according to the dielectric measuring principle. Fields of
application include the non-destructive moisture measurement
of sawn timber, lumber and firewood as well as of mineral
building materials.
The dielectric measuring method is an indirect measurement
method, since the moisture content of the measured material is
deduced from the changed dielectric permittivity.
Influencing variables suitable to change this parameter, e.g.
electrically conducting materials or dissolved salts, hence also
have a direct influence on the determined measured values.
Since the exact composition of building materials is generally
unknown before a moisture measurement, the displayed
measured values can only be regarded as an indicator of the
moisture content.
General notes on use
Calibration curves for measuring the moisture level in different
mineral building materials, hardwood, softwood and chipboard
are stored in the device. If precise material moisture values are
required, an additional control measurement applying the Darr
procedure is recommended. Especially for precise wood
moisture measurements for other wood temperatures or with
due regard to the type and bulk density of a certain timber it is
recommended to use a wood moisture measuring device with
temperature comparison function and selection option for the
specific wood type calibration.
• When selecting the measuring positions observe the
following:
– Always measure the material moisture at three different
positions in order to achieve a sufficient accuracy by
means of the arithmetic average.
– Do not measure the face, because there are mainly dry
areas.
– Preferably do not measure at cracks, branches or resin
pockets either.
Notes on use regarding the material moisture measurement
No further settings are required for the quick determination of
the material moisture at the device. Nevertheless, when
assessing the measurement results one has to bear in mind that
the results can be influenced by various factors.
• The measurement's accuracy depends on the contact
pressure of the measuring electrodes. Ideally, they should
be applied with a steady contact pressure of approx. 10N
(this corresponds to approx. 1kg of weight force), however
not bent to the point of overlapping.

EN 17

• Measuring depth
– Depending on the material's bulk density and degree of
moisture penetration, the device's penetration depth
ranges up to 40 mm. Conclusions regarding zones
located at a lower level cannot be drawn.
• Material characteristics
– Increased occurrences of soluble salts in the measured
material can distort the result of the measurement. The
more salts present, the higher the conductivity of the
material and the higher will be the displayed
measurement value.
– If possible, do not measure wood with a temperature
below -5°C. Too low wood temperatures distort the
result of the measurement.
– The material should be preferably homogenous and not
have any air pockets.
• Electrically conducting materials or electrical fields
– If a construction material contains electrically
conducting substances, the dielectric constant is also
increased, which then simulates high moisture values.
Consequently, a too high measured value will be
displayed.
– From visual inspection it is not always apparent,
whether there are any electrically conducting
substances inside the construction material. Some of
the main error sources here are in particular
reinforcements, metal laminations and conducting
insulation such as slag in timber beam ceiling
constructions. Especially in case of insulation materials
with metal lamination, measured values are often
misinterpreted.
– Avoid static charge of the material to be measured due
to friction. Static charge distorts the measurement
result.
– With a wood moisture of less than 10%RH,
electrostatic forces may occur at the good to be
measured. This can falsify the result of the
measurement. Experience has shown that this occurs at
the outlet of veneer drying plants. Remove the static
charge by use of suitable grounding measures.
– For optimum conditions neither electrical fields nor
conducting materials should be present.
• Surface condition
– Oily and/or aqueous timber preservatives affect the
measurement result.
– The surface of the material to be measured should be
as level as possible to permit thorough contact of the
measuring probe.
• Moisture distribution
– With material thicknesses of less than 2 cm there is a
danger of humidity values from adjacent material layers
affecting the measured value.
– Ideally, the moisture should be evenly distributed within
the material to be measured.
Quantitative conclusions about the moisture content of the
mineral material to be measured can only be drawn by applying
the Darrprocedure or the CMmethod.
Maintenance and repair
Battery change
A battery change is required when the LED at the appSensor
flashes red or the sensor can no longer be switched on. See
chapter Operation.
Cleaning
Clean the device with a soft, damp and lint-free cloth. Make
sure that no moisture enters the housing. Do not use any
sprays, solvents, alcohol-based cleaning agents or abrasive
cleaners, but only clean water to moisten the cloth.
Repair
Do not modify the device or install any spare parts. For repairs
or device testing, contact the manufacturer.

Errors and faults
The device has been checked for proper functioning several
times during production. If malfunctions occur nonetheless,
check the device according to the following list.
Bluetooth connection is terminated or interrupted
• Check whether the LED at the appSensor flashes green.
If so, briefly switch it off completely, then turn it back on.
Establish a new connection to the terminal device.
• Check the battery voltage and insert new or freshly
charged batteries, if required.
• Does the distance between appSensor and terminal device
exceed the appSensor's radio range (see chapter Technical
data) or are there any solid building parts (walls, pillars
etc.) situated between appSensor and terminal device?
Shorten the distance between the two devices and ensure
a direct line of sight.
The sensor cannot be connected to the terminal device
although it is displayed there.
• Check the Bluetooth settings of your terminal device.
A possible reason for this could be special, manufacturer-
specific settings relating to an improved location accuracy.
Enable these settings, then try to establish a connection to
the sensor again.
Further information and assistance regarding the used sensor
type will be provided in the MultiMeasure Mobile app via the
