Proper use
The moisture meter is only designed for use as a mul-
tifunction instrument with materials like wood, stone,
concrete etc. It measures the water content of the ma-
terial based on conductivity associated with the pres-
ence of water in the material. The moisture meter is
only intended for private use and not suitable for com-
mercial purposes.
Only use the moisture meter as described in this user
manual. Any other use is considered improper and may
result in personal injury or damage to property.
Only use the moisture meter as recommended by the
manufacturer. Failing to do so may negatively affect the
safety protection features.
The manufacturer or vendor accepts no liability for
damage caused by improper or incorrect use.
Safety notes

WARNING!
Risk of explosion and chemical burns!
Handling batteries improperly may result in
explosion or chemical burns.
−
Only use batteries of the same type:
6F22/6LR61.
− Do not recharge the batteries or reactivate
them with other means.
− Make sure that the polarity is correct when
inserting the batteries.
− Do not take the batteries apart.
− Store the batteries in a cool, dry place. Do
not subject the batteries to excessive heat
(e.g. from direct sunlight) and do not dis-
pose of them in fi re.
− Do not short circuit the batteries.
− Do not allow batteries to come into contact
with your eyes or mucus membranes. In the
event of contact with battery acid, immedi-
ately fl ush the applicable areas with plenty
of clean water and consult a physician.
− If someone has swallowed a battery, he/
she must immediately contact a physician.
Safety
9
− Clean the battery and the device contacts
before inserting it.
− Take the empty battery out of the moisture
meter. There is a risk of battery acid leaking.
− Take the battery out of the moisture meter
if you do not use it for a prolonged period of
time.
− Remove the battery before disposing of the
moisture meter.
NOTICE!
Risk of damage!
Improper handling of the
moisture meter
may result in damage to the
moisture meter
.
− Protect the moisture meter from dust, severe
heat, cold and severe vibrations and shocks.
− Do not expose the moisture meter to drip-
ping water or splashes.
− Do not submerge the moisture meter in wa-
ter or other liquids.
− Do not use the moisture meter if it is dam-
aged.
− Do not make any modifi cations to the mois-
ture meter.
Safety
10
− Never attempt to open the moisture meter
or insert metallic objects inside it.
− Only have qualifi ed personnel perform re-
pairs. Observe the warranty conditions.

Checking the sensor and
product contents
NOTICE!
Risk of damage!
If you are not cautious when opening the
packaging with a sharp knife or other pointy
object, you may quickly damage the
mois-
ture meter
.
− Be very careful when opening.
1. Take the moisture meter and the battery out of the
packaging.
2. Check whether the moisture meter or the battery ex-
hibit damage. If this is the case, do not use the moisture
meter. Contact the manufacturer at the service address
specifi ed on the warranty card.
3. Check to make sure that the delivery is complete (see
Scope of delivery).
4. Remove the protective fi lm.

Operation
Inserting the battery

(6F22/6LR61)
9 V
1. Open the battery compartment cover 3 on the back of
the moisture meter.
2. Insert the battery in the battery compartment. Make
sure the terminals are aligned correctly.
3. Close the battery compartment cover.
Operation
13
Before taking the measurement
1. Use a dry cloth to get rid of wet residue on the surface of
the material.
2. Remove any salt on the surface of the material. Salts
increase the conductivity of water and falsify the meas-
urement result.
3. Remove the bark from fi rewood if applicable and split it
in the middle.
4. Push the probe 4 perpendicular to the direction of
fi bre in the wood and measure at multiple points. For
example, 5 – 10 cm away from the saw edges and in the
middle.

If the probes are inserted in the direction of the fi bre,
slightly elevated measurements can result.

Operation
Taking a measurement
CAUTION!
Risk of injury!
The probes of the moisture meters are pointy.
You cou ld prick and injure yourself.
− Never point the probes at other persons
and animals.
− After use, put the protective cap on the
probes.
NOTICE!
Risk of damage!
The probes are pointy. You can damage the
material and leave holes.
− With sensitive materials, take measure-
ments in an inconspicuous area. The softer
the material, the more likely it is that the
probes will leave behind holes.
The moisture meter only measures up to the depth you
insert the probes in the material. The probes 4 must be
fi rmly pressed into the material to be measured and pen-
etrate the wood, the plaster etc.

T he display shows 0.0 %, the ambient temperature in
°C and the selected material (1 – 6). See the table at the
end of this chapter.
The temperature display can be switched between °C
and °F. To do so, press and hold the lock button ( ) 6
for about 3 seconds.
2. To set the moisture meter to the material you intend to
measure, push the mode button 5 repeatedly until the
correct number is shown on the display. See the table at
the end of this chapter.
3. Take the protective cap off 8.
4. Push both probes into the surface of the material at the
same time.

Operation
After 1 – 2 seconds, the percentage will be shown.
With rough surfaces, apply more pressure to the probes
if necessary. You do not have to apply excessive force to
get a correct result.
For measurements below the measurement range, 0.0
% or LO will appear on the display. HI is displayed for
measurements above the measurement range.
5. Take measurements on various areas of the surface and
determine a mean value. Add all measurements to-
gether and divide the result by the number of measure-
ments.
If you are measuring a natural product, the same mate-
rials from different batches may return different results.
6. If you take a measurement in one area where the dis-
play cannot be read, press the lock button ( ) 6.
The reading is saved and the lock symbol () appears.

8. To switch the moisture meter off, push the On/Off button
() and put the protective cap back on the probes.
Automatic switch-off: The moisture meter will also auto-
matically switch off after being inactive for 60 seconds.

Cleaning and storage
NOTICE!
Risk of short circuit!
Water that has penetrated the housing may
cause a short circuit.
− Never immerse the moisture meter in wa-
ter.
− Make sure that no water penetrates the
housing.
NOTICE!
Risk of damage!
Improper handling of the moisture meter
may result in damage.
− Do not use any aggressive cleaners, brush-
es with metal or nylon bristles, as well as
sharp or metallic cleaning utensils such
as knives, hard scrapers and the like. They
could damage the surfaces.
Cleaning and storage
20
− Do not in any case place the sensor in the
dishwasher. It would be destroyed as a
result.
1. Always keep the probes free from material residue of
any kind.
2. Only wipe the moisture meter off with a damp cloth and
a small amount of detergent.
3. Carefully dry all wet areas, then let all parts dry com-
pletely.
4. Remove the battery during longer periods of non-use.
5. Store the moisture meter in a dry, frost-free location
indoors out of the reach of children.
