wood it is best, if to pull it out, you slide something (like

a screwdriver) between the electrode and the wood. This
will prevent the needles from bending.

(b) It is also possible to beat the hammer electrode into the

wood with a normal hammer.

(c) When measuring a very thick timber you can use nails of

appropriate length and 2-3 mm. You should beat the
nails into the wood. The distance between them should be
25 mm. A line drawn between them should be per­pendicular to the fibres in the wood Then touch the nail
heads' with the needles of the hand electrode, turn on the
moisture meter and read the result. However the
measurement done in this way is less accurate.

(d) When measuring a very dry wood:

- do the measurements in a place where the electro­magnetic interference is minimal (away from electric
engines, high voltage wires etc.),

- do not move the device or it's cable during the
measurement,

- use as thin needles as possible as they provide a better
contact with the wood.

1. DECRIPTION AND APPLICATIONS

Wood Moisture Meter WRD-100 is a sophisticated electronic
device for measuring moisture in wood from 6% to 100% of
moisture contents. It can measure moisture in 11 different
types of wood: pine, spruce, fir, great maple, birch, maple,
ash, walnut, oak, beech and poplar. The Moisture Meter is
equipped with temperature compensation control knob. The
Moisture Meter is also equipped with a hand and a Hammer
Electrode and in addition it can be equipped with an Inertial
Electrode EB-1

Moisture Meter WRD-100 is widely used in wood industry,
forestry and other industries utilising wood.

3. PREPARING THE INSTRUMENT

- Before the measurement you should connect the moisture
meter with one of the electrodes. with coaxial cable
provided.

- Set the "WOOD TYPE" switch to the appropriate wood
type and the "WOOD TEMPERATURE" switch to the
measured (or approximate) wood temperature.

4. SELECTING THE ELECTRODE

- We recommend that the length of the needles you use
should be about 25-30 % of the thickness of the timber.

- To measure wood with a high moisture contents you
should use the hammer electrode with long needles. A dry
wood should be measured with the hand electrode (or the
hammer electrode with short needles).

5. MEASUREMENT

To conduct measurements do the following:

- Beat the electrode into the wood. A line drawn between
the needles should be perpendicular to the fibres in the
wood.

- Press the power switch.

- Read the result on the LCD.

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.

While conducting the measurements you should observe the
following rules:

- Do the measurement in the middle of the timber not closer
than 0.5 m from each end.

- Do not make the measurements where there are defects in
the wood.

- You should make from 2 to 4 measurements on each side
of the timber.

- 4 -

- In each spot you should make not less than 3 separate
measurements 10 - 15 mm apart.

- The final result is the arithmetic average of the results.

6. MEASURING VERY DRY WOOD

Measurements of moisture contents in a very dry wood
(below 10%) are subject to interference. This can be observed
when the result of the measurement becomes unstable. The
sources of the interference are electrostatic charges and
electromagnetic fields. Often the measurements of very dry
wood are conducted in a very dry environment (below 30%
RH) and this additionally increases the problem.
When measuring a very dry wood:

- do the measurements in a place where the electro­magnetic interference is minimal (away from electric
engines, high voltage wires etc.),

- do not walk around the device,

- use thin needles because they provide a better contact
with the wood,

- in extremely difficult conditions place the timber on a
grounded metal plate or wire mesh.

7. CHANGING 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.

8. ADDITIONAL INFORMATION.
(a) The most common cause of bending or breaking the

needles in the hammer electrode is an incorrect way of
pulling it out of the wood. With long needles and hard
