Hydromette BL A plus
5.1.2
Notes for capacitive measurement
Measurements with the Hydromette BL A plus must not be
performed on a conductive surface (e.g. metal). For wood
thicknesses of less than 40 mm (e.g. veneers, strips, etc.), either
several layers must be laid on top of each other until a minimum
thickness of 40 mm is reached, or the selection for thin material
thicknesses must be selected in the menu. In the second case
there must be air or e.g. Styrodur underneath the measuring point.
The measurement is based on the principle of the capacitive
electric field. The active measuring electrode is located on the
bottom of the device. In order to prevent the operator's hand from
influencing the measurement process, the device may only be held
at the lower part during both measurement and functional check.
Never touch the device near the active measuring electrode during
measurement or check. Do not measure in the area of knots and
twists as well as through bark or cambium.
