Operating Instructions FMC/FME moisture meter
5.4 Precautions and instructions
The insulated measuring pins should be hit into a depth of 1/3 of the
wood thickness.
The meter measures the resistance between the two measuring pins.
Cracks, resin channels, knots, etc. may affect the moisture
measurement.
In certain weather conditions, condensation may occur on the
measuring electrode. The FMC/E will then display a higher
measurement value. The measurement electrode should be dry and
placed in the measuring area for a few minutes to allow it to acclimatise
to the ambient temperature.
If the wood is extremely dry and the relative air humidity is low, static
electricity may cause problems. In that case, the meter should be laid
on the material being measured and not held.
In some cases, the measurement value in the meter display may fall.
This may occur, for example, if the wood has been impregnated or been
in contact with salt-water. The measurement should then be taken in
another part of the wood.
