Wood moisture content meter is made for
quick reading of wood moisture by simple pressing
on flat wooden surface.
There is a specially designed sensor plate on the
back side of the meter which measures wood MC
when pressed on the wood surface.
In order to achieve accurate measuring data using
this meter it is required to perform certain procedures
before measurement such as autocalibration and
basic parameter adjustments. Following chapters of
this manual will contain more information th
procedures.

Device is placed in the plastic case with large display
for indication of all measurement data and flat
keyboard for device control.

4. TURNING METER ON / OFF AND AUTOCALIBRATION PROCEDURE
Turning the meter ON
It is essentially important to ensure that meter during autocalibration has
such position that sensor plate hangs free in the air, i.e. there is nothing
behind sensor plate blocking it! Do not hold fingers or other objects behind
sensor plate during autocalibration. Existence of any object near sensor
plate during autocalibration procedure can corrupt this process and result
in inaccurate measurement and measuring errors.

functions immediately after powering on. When the button is pressed, message
After a few seconds, when autocalibration procedure is finished, meter will

is displayed for few seconds.
During this time, meter is performing procedure, i.e. series of test-measurements
required for its adaptation to current operating conditions (ambient temperature, air humidity, etc).
which signals that it is ready for measurement or other adjustments.
Autocalibration procedure is performed each time the meter is powered ON,
which ensures reliability of measurement in all declared conditions.

When it is turned off, the meter does not consume energy from the
battery
If there is any doubt in measuring accuracy and possible error in autocalibration as a cause of false
measurement, autocalibration should be repeated by simple turning off and turning on the meter again.
Meter can detect large calibration errors itself. In this situation, after removing all objects away from back side
of the meter (so it "measures air"), message is displayed.
