4.1. Procedure

1. Remove the protective cover from the prods. Then switches the
instrument on; you will notice the "on" indicator lamp lights up.
Note that the measuring prods may cause injury if not handled with
caution.
2. Insert the prods fi rmly into the material and read the measurement
result:
For wood, insert the prods so that the current circulates parallel to
the wood fi bres.
If the material moisture level is less than 6%, none of the LEDs light up.
If the percentage is between 6 and 23%, take the reading directly from
the right-hand column opposite the LED which is lit.
If the percentage is over 23%, the top LED will light up, indicating that
you should press on the red button on the front of the instrument. Then
read the percentage (between 24 and 100%) indicated in the left-hand
column opposite the LED which is lit.
Since the measurement result depends on the density and nature of
the material, its value is essentially one of comparison between the
dry and moist condition of this material.
3. To switch the instrument off, simply replace the protective cover.
4. If the "Low Batt." LED stays continuously lit, this means the battery
should be changed straight away.

4.2. Measuring precautions

The surface of the material must be dry otherwise the measurement
result will be incorrect. It is in fact the internal percentage of moisture in
the material that we wish to determine.

5. CHARACTERISTICS
