5. Replacing the batteries and storage
The instrument is equipped with a power level control
unit. When the power drops below acceptable level a sign
"LO BAT" appears on the left side of the LCD. This
indicates that the battery has expired and should be replaced
with a new one.
To replace the battery unscrew the screw on the back
of the instrument and carefully remove the back panel.
Store the device in a dry place.

UNIVERSAL MOISTURE
METER WIM-90
USERS MANUAL
1. .Description and applications
The Universal Moisture Meter WIM-90 is an
electronic device for measuring air humidity and moisture
contents in wood and concrete without any tables and
calculations. Such wide range of applications is possible due
to a large number of electrodes that come with the
instrument.
WIM-90 is widely used in wood and building
industries.
2. Wood moisture contents
2.1. Technical data
Measuring range 6% - 100% of most. cont.
No. of wood types 11
Wood temp. range 0° - 50°C
Display type LCD
Power 1 * 9V (1 battery 6F22)
2.2. Preparing the instrument for measurements
•Before the measurements connect the instrument with
the electrode. Use the cable with the BNC plugs. A
secure connection can be obtained by firmly plugging
the plug into the socket and turning the external ring of
the plug clockwise.

•Select the correct wood type with the WOOD TYPE
knob and set the TEMPERATURE COMPENSATION
knob to the appropriate (measured or approximated)
wood temperature.
2.3. Conducting wood moisture cont. measurements
To conduct measurements:
•Beat the electrode into the wood. A line drawn between
the needles should be perpendicular to the fibers (the
resistance should be measured across the fibers).
•Press the power button located near the BNC socket.
•Read the result.
(If the moisture contents is lower than 6% a sign „LO”
appears on the LCD, if the moisture contents is higher
than 99.9% - „HI” is displayed.)
3. Concrete moisture contents
3.1. Technical data
The measurement of moisture contents in concrete is
based on the measurement of the resistance and complies
with the British Standard BS.5352;1983.
Measuring range 1% - 10%
Accuracy
within the range
of 0% - 5% 0.5%
above 5% 1% - 1.5%
The resistance characteristics have been selected
during research and development.

3.2. Preparing the instrument for measurements
Before the measurement drill two holes in the
concrete floor 10 mm in diameter and 40 mm deep. The
distance between the holes should be 10 cm. Put the
electrodes into the holes and fasten them by tightening their
nuts. The torque applied to the nut should be appropriate to
the hardness of the concrete floor. The older the concrete
floor (harder) the higher the torque can be. Do not crumble
the concrete floor. The measurements should be conducted
in several places of the floor.
3.3 Conducting concrete moisture cont. measurements
To conduct measurements:
•Connect the electrodes with the instrument using a cable
with appropriate connectors.
•Set the WOOD TYPE knob to “CONCRETE”.
•Set The TEMPERATURE knob to 20°C.
•Press the power button located near the BNC socket.
•Read the result.
(If the moisture contents is higher than 10% a sign „HI”
appears on the LCD)
Warning:
•For concrete moisture contents measurements the
TEMPERATURE COMPENSATION knob must be set
to 20°C.
•With high moisture contents values (above 6 - 7%) the
result may “float” a little –it will slowly decrease. The
result observed 1.5 minutes after turning the device on
should be considered as the final result.

4. Air humidity
4.1. Technical data
The measurement of air humidity is conducted using
a chemical sensor (cellulose compound). This allows for an
approximate measurement of air humidity in storage rooms,
production houses etc.
Measuring range 30% - 90% RH
Accuracy 3% - 4%
4.2. Preparing the instrument for measurements
Place the SC1 sensor in the room where the air
humidity should be measured at least 8 hours before the
measurement.
4.3. Conducting the air humidity measurement
To conduct the measurement:
•Plug the SC1 sensor into the instrument.
•Set the WOOD TYPE knob to “AIR HUMIDITY”.
•Set The TEMPERATURE knob to 20°C.
•Press the power button.
•Read the result when it stabilizes.
(If the moisture contents is lower than 30% a sign „LO”
appears on the LCD, if the moisture contents is higher
than 99.9% - „HI” is displayed.)
Warning:
•For air humidity measurements the TEMPERATURE
COMPENSATION knob must be set to 20°C.
