Before rst use
Open the battery compartment cover (6) in the direction of the
arrow and remove the protective paper between the contacts
and the battery (8). Connect the contacts to the battery and
put the battery compartment cover (6) back on. The device is
now ready to use.
Operating the wood moisture meter
Push the cap (5) tab where it says (UP) and take off the cap.
Press the ON/OFF switch (1).
Press the two test pins (7) into the wood surface with slight
pressure. The moisture content of the wood will be shown on
the display (3) in percent.
The reading can be stored until the next measurement by
pressing the memory button (2). Pressing the button again
deletes the reading.
To get a correct reading of the inside of the wood, split it and
measure the interior surface. Take readings at 3 places to get
an average. The meter can be used on all wood surfaces.
After measurement is completed switch the meter off and put
the cap (5) back on!
Readings for rewood:
5-15 % = Very good for heating
16-20 % = Can be used for heating with some limitations
21-40 % = Not suitable. Needs further drying.
