cover and screw it back in place
•
Replace the battery when the low
battery indicator [9] lights up on
the LC display
•
To change the battery, proceed
as described above. However,
remove the used battery from
the contacts and the battery
compartment before inserting a
new one.
7.0 Commissioning
NOTE
Ensure that the humidity
measuring unit is switched o
before changing the battery.
General notes before starting
measuring
•
The displayed humidity level is
an average value determined by
the moisture on the outer surface
as well as inside the material.
If there is any visible surface
moisture or water, wipe it o
and allow the surface to dry for
a few minutes before starting
themeasurement
•
Other factors can also inuence
the measurement. Before the
measurement, the corresponding
surface must be cleaned of any
paint residues, dust, etc
•
Before measurement, the
measuring point must be cleared
of impurities (e.g. dust and other
loose components).
•
If the measured material contains
metal (e.g. nails, screws, leads,
pipes, etc.) and this is located in
the measuring eld of the sensor,
the measured value increases
abruptly due to strong reections
•
If the spherical head is held in
corners (e.g. tile joints or window
niches), the measured value is
generally higher because there is
more substance in the scattering
eld of the measuring head
•
There must be a distance of more
than 8 to 10 cm from the corner
•
Hold the measuring unit at its
outermost end as far away as
possible from the ball head of
the humidity sensor [1] to avoid a
possible inuence of humidity by
your hand on the measured value
8.0 Use
•
The measuring unit is not suitable
for measuring metal or other
highly conductive materials.
If there is metal enclosed in
the material (e.g. nails, screws,
cables, pipes, etc.) in the sensor's
measuring range, the measured
values increase considerably
•
If the humidity sensor [1] is
placed in a corner of the wall,
themeasured values may be
higher because there are two or
three surfaces in the measuring
range.
Keep a minimum distance of 8
to 10 cm from other surfaces to
avoid interference
•
Place the humidity sensor [1] on
smooth surfaces. Rough surfaces
lead to inaccurate measurement
results
•
The measuring depth of the
unit ranges from 20 to 40 mm.
Depending on the density of
thematerial, a measurement
of the inner core may not be
possible. If the material is less
than 2 cm thick, the measured
value of the humidity level may
be inaccurate due to adjacent
material
•
The humidity sensor [1] must be
held at right angles directly to
thesurface to be measured
•
The density of the measured
material plays an important role
for the measurement result.
Themeasured value increases
with the respective density
•
An important area of application
for this unit is comparative
measurements, where the
measured value is compared with
a reference value. Thereference
value is determined by

Switching on and o
•
To switch on, press the on/o
key [6] when the measuring unit
is switched o. To switch o,
press the on/o key [6] when
themeasuring unit is switched
on.
Humidity level measurement
•
Switch on the measuring unit by
pressing the on/o key [6]
•
The measuring unit must be
calibrated each time it is switched
on. Hold the measuring unit in
the air for calibration so that
thehumidity sensor [1] does not
touch any objects. The minimum
distance from any surface or
your hand to the ball head of the
humidity sensor [1] should be 8
to 10 cm
NOTE
If you have calibrated
the measuring unit for a
measurement, do not change
the position of the hand in
thesubsequent measurement.
Measurement calibration and
measurement must be carried
out with the same hand position,
because a change in the position
of the hand, relative to the ball
head of the humidity sensor [1],
leads to measuring errors.
•
The calibration must always
be carried out again after each
new switch-on as well as each
change of the measuring point or
themeasured object!
•
Hold the ball head of
thehumidity sensor [1] at right
angles to the surface.
The display shows the measured
value (current humidity level
[18]).
•
Move the measuring unit to take
measurements of a larger surface.
The LC display should show the
current measured value as well as
the maximum [16] and minimum
[15] measured values.
•
If necessary, press the MEAS
key [5] to freeze a value on
thedisplay.“HOLD”[10] appears
on the display in addition
to thelast measured value.
If the“HOLD” mode is not
terminated by pressing the MEAS
key [5], the measured values
are shown on the LC display
for another 30 seconds before
the measuring unit switches o
automatically.
•
Before this time has elapsed,
press the MEAS key (5) in“HOLD”
mode to exit“HOLD”mode and
perform further measuring
procedures.
•
After nishing your
measurements, switch o the
measuring unit by pressing the
on/o key [6]. If the measuring
unit is not switched o, it will
automatically switch itself o
after a period of 10 minutes. To
do this, it must not be in“HOLD”
mode
NOTE
There is a 1/4" (6.3 mm) screw
terminal on the back of the
measuring unit for attaching
the measuring unit to suitable
holding devices such as tripods.
This allows measurements
to be taken on the stationary
measuring unit by dragging the
smaller part to be measured past
the probe.
NOTE
Measuring head may leave black
marks on light-coloured walls
or wallpaper. Please place the
measuring head carefully on
sensitive surfaces
measuring in a clearly dry area of
a similar or identical material. If
the subsequent measurements
are signicantly higher than
the reference value, it can be
concluded that the measuring
ranges are wet. This method is
very well suited for assessing
water damage, locating leaks and
areas of high humidity
•
Press the MEAS key (5) to start
the calibration procedure. The
LC display shows“CA”during
calibration
•
After calibration, the LC display
[2] shows the current humidity
level [18]. This calibration value
should be“0”. If not, switch o
the measuring unit and repeat
the calibration procedure after
switching it on again.

The diagram opposite illustrates
the corrosion rate, e.g. for metal,
at dierent humidity levels. It can
be seen that the corrosion rate is
insignicant below 50 % relative
humidity (RH) and negligible below
40 % RH.
The corrosion rate increases
signicantly above 60% RH. This
threshold for damage as the
result of humidity also applies to
other materials, such as powdery
substances, packaging, wood and
electronic units.
Buildings may be dried in a variety
of ways:
The correlations occurring when
air is dehumidied are based on
physical laws.
These are depicted here in graphical
form in order to provide you with a
brief overview of the principles of
air dehumidication.
Using
Climia air dehumidiers
•
Even if windows and doors
are well insulated, water and
moisture are still capable of
penetrating thick concrete walls.
•
The water required for setting
in the production of concrete,
mortar and plaster etc. may only
be diused after 1-2 months.
•
Even moisture trapped in the
masonry after high-water or a
ood is released very slowly.
•
The same is also true of moisture
contained in stored materials for
example.
The moisture (water vapour)
released from parts of a building
or materials is absorbed by the
surrounding air. As a result, the
moisture content increases, which
ultimately gives rise to corrosion,
mould, rot, peeling of paint and
other unwanted damage.
12.0 Air dehumidication
Corrosion rate
Rel. humidity %
1. By heating and
air exchange:
The air in the room is heated
in order for moisture to be
removed and then this air is fed
outside. All of the energy that
is involved is lost together with
themoist air that is released.
2. By air dehumidication:
The moist air that is present
within an enclosed space is
continuously dehumidied
according to the condensation
principle.

12
CLIMIA
With regard to energy consumption,
air dehumidication has one
distinct advantage:
Energy expenditure is limited
exclusively to the air volumes
present. The mechanical heat that
is released by the dehumidication
process is fed back into the room.
Under normal use, the
air dehumidier
uses
approximately 25% of the
energy that is required for
the
"heating and ventilating"
principle.
Relative air humidity
Our ambient air is a gaseous
mixture which always contains a
certain volume of water in the form
of water vapour. This volume of
water is specied in g per kg of dry
air (absolute moisture content).
1m3of air weighs approx. 1.2 kg at
20°C
Depending on the temperature,
each kg of air is only capable of
absorbing a certain volume of
water vapour. Once this capacity
has been reached, the air is referred
to as“saturated”and has a relative
humidity (RH) of 100%.
Relative humidity is understood to
mean the ratio between the current
quantity of water vapour in the air
and the maximum possible quantity
of water vapour at the same
temperature.
The ability of the air to absorb water
vapour increases as the temperature
rises. I.e. the maximum possible
(absolute) water content becomes
greater as the temperature rises.
Building materials and structures
are capable of absorbing
considerable volumes of water, such
as brick 90-190 l/m³, heavy concrete
140-190 l/m³ and limestone 180-270
l/m³.
The drying of moist materials such
as masonry is eected as follows:
•
The moisture
)moves from
the inside of
the material to
its surface
•
Evaporation occurs on the
surface = Transfer of water
vapour to the ambient air
•
The air containing water vapour
is constantly circulated through
the air dehumidier. The air
is dehumidied and, slightly
heated, leaves the unit in order
to re-absorb water vapour
•
In this way, the moisture
contained in the material is
reduced gradually.
The material is dried!
The accumulated condensate is
collected in the unit and drained o
from there.

Humidity measuring unit CMG 100
Water vapour condensation
Because the capacity for the
maximum possible volume of
water vapour increases as the air is
heated, the volume of water vapour
contained remains constant and so
relative humidity falls.
In contrast, because the capacity for
the maximum possible volume of
water vapour decreases as the air is
cooled, the volume of water vapour
contained remains constant and so
relative humidity increases.
If the temperature continues to
fall, the capacity for the maximum
possible volume of water vapour
is reduced so much so that it is
ultimately equal to the volume of
water vapour contained in the air.
This temperature is referred to as
the dew point. If the air is cooled
to below dew point, the volume of
water vapour in the air will become
greater than the maximum possible
volume of water vapour.
At this point, the water vapour
begins to precipitate.
This condenses to water and
moisture is removed from the air.
Examples of condensation include
steamed-up window panes in
winter, or the moisture on the
outside of a cold drinks bottle.
As the relative
humidity of the air increases, so too
does the dew point, making it easier
for the temperature to fall below it.
Condensation heat
The energy transferred to the air
from the condenser consists of:
1. The amount of heat derived
beforehand in the evaporator.
2. The electrical drive energy.
3. The condensation heat released
by liquefying the water vapour.
Energy must be supplied when
liquid is converted into a gas. This
energy is designated as evaporation
heat. It does not cause any increase
in temperature, but is required
to convert a liquid into a gas.
Conversely, energy is released when
gas is liqueed, this is designated as
condensation heat.
The amount of energy from
evaporation heat and condensation
heat is the same.
For water, this is:
2250 kJ/kg (4.18 kJ = 1kcal)
From this it is evident that the
condensation of water vapour
causes a large quantity of energy to
be released.
If the moisture that it is to be
condensed is not introduced by
evaporation in the room itself,
but from outside, e.g. through
ventilation, the condensation heat
released contributes to the heating
of the room. With drying operations,
a heat cycle is created, whereby
heat is consumed for evaporation
and released for condensation.
When dehumidifying fed air, a
larger contribution of heat is
created, which manifests itself as a
temperature increase.
Generally speaking, the time
required for the drying process is
not only dependent on the output
of the unit, but is determined to
a greater extent by the speed at
which the material or building
section loses its moisture.
