2.1 Intended use
This device uses the capacitive measurement principle
and is used for non-destructive location and evaluation
of moisture distribution in walls, oors and ceilings, it
provides an oveiew of the extent, distribution and
severity of the moisture damage as pa of a building
suey. It can be used in the material-independent
INDEX mode or the additional 4 types building material
mode(concrete, cement, plaster and wood).
Building materials of the same type but with
dierent designation/composition/strength/
density may aect the measurement result.
Fuhermore, building materials will va from
manufacturer to manufacturer due to the way they
are produced. This is why, when we measuring
unfamiliar building materials, the measured values
may dier from the actual values. If dierent
measured values occur, the reading should be
viewed as relative values or use the index mode.
For the 4 types building material mode, the reading is
mass%, it is based on the d mass of the measured
material. The moisture content is calculated according
to the following formula: moisture content in mass% =
(mass of water contained in the material / d mass of
the material)x100%. Example: 600g material contains
100g water=20% moisture content.

INDEX mode
Index mode is used to rapidly locate moisture with
comparative measurements. The output value (0 ~ 100)
is an indexed value that increases as material moisture
becomes greater. Measurements made in index mode
are independent of material type and paicularly useful
with materials for which no characteristics are stored.
Press the button " " to calibrate first, and then press
the button " " to select the INDEX mode.

Reminder on use
Eve time resta the device, it is always
need to be calibrated to zero in mid-air to
compensate environmental inuences,
otherwise the device cannot be used.
Calibration method:
Press the button " ", then the word " " will appear
on the LCD and ashes. During calibration, the Probe
must not be in contact with the user's hands or other
objects.
During
calibration,
keep the
probe away
from any
object at
least 10cm
EN-07
The device has a data hold function and can turn o
the LCD backlight.
Note:
If the probe contact with an object accidentally during
calibration, its moisture will be stored as zero base ,
which will result in a low or zero value measured by the
device. If this event occurs, please recalibrate in the
correct way.

4. Dielectric measurement and notes
Dielectric measurement is an indirect measurement
method, the dielectric permittivity of the measured
material changes with the change of moisture content,
the moisture content of the measured material is
deduced from the changed dielectric permittivity.
The dielectric measurement method can only roughly
measure the moisture value of the material. The
measurement results can be inuenced by various
factors.
When the probe is held to corners (e.g. window
frames), the measured value is generally higher,
because there is more matter in the measuring
probe's stray eld. Toward a corner a distance of
less than 10cm has to be obseed.
When peorming the measurement, always hold
the probe perpendicular to the material to be
measured. Press the probe rmly against the
suace to be measured and make sure not to tilt it.
Peorming the measurement
EN-09
Depending on the
material's bulk density
and degree of moisture
penetration, the
device's penetration
depth 5 ~ 40 mm.
Ensure the materials
thickness 5mm, ≥
otherwise, the device
may have no reading.
Measuring depth
Material characteristics
Increased occurrences of soluble salts in the
measured material can disto 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 disto the result of the
measurement.
The material should be preferably homogenous
and not have any air pockets.
Electrically conducting materials or electrical elds
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.
Measuring depth
5~40mm
Ensure the measured materials
thickness greater than 5mm
Avoid static charge of the material to be measured
due to friction. Static charge distos the
measurement result.
lf the material to be
measured contains metal
(e.g. nails, screws, lines,
pipes, etc.) and is situated
within the sensor's
measuring eld, the
measured value skyrockets
due to intense reections.
Avoid
metal
EN-10
The readings can be inuenced by nearby metal,
or your own ngers. Keep at least 5cm distance
from metal . Keep ngers in the narrower pa of
the bottom when using , well clear of sensor.
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 paicular
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.
Suace condition
Before measuring, the measuring point is to be
cleared of any impurities (e.g. paint residues, dust).
Oily and/or aqueous timber preseatives aect
the measurement result.
Rough suaces will always result in a too low
measured value.
The suace of the material to be measured should
be as level as possible to permit thorough contact
of the measuring probe.
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 ding plants.
Remove the static charge by use of suitable
grounding measures.
For optimum conditions neither electrical elds
nor conducting materials should be present.
=Avoid
EN-11
Moisture distribution
With material thicknesses of less than 2cm there is
a danger of humidity values from adjacent
material layers aecting the measured value.
For optimum conditions, the moisture should be
evenly distributed within the material to be
measured.
Water
Water attached
to the surface of
the material
Do not use this device measure water or water
attached to the surface of the material that has
not yet been immersed in the material, it is
pointless. Because it is not a instrument which can
detect the presence of water molecules, it works
according to the principle that the dielectric
constant of the material changes with the change
of humidity.
For transpoing the device use a suitable bag to
protect it from external inuences.
