5. al s moisture level and its dielectric constant and therefore its capacitance 2 The so called fringe field effect the slight spreading of the electric field produced by current flow between two electrodes when both electrodes are on the same side of a material Behind the back cover of the MMD5NP are two metal plates When the meter is powered on the plates are given small and opposite charges The potential difference causes current to flow creating a three dimensional electric field When the back of the meter is placed against one side of a material with moisture on or slightly below its surface the increased capacitance of the material distorts the electric field to an extent that can be sensed as a change in flux over the sensing area and measured Displayed readings reflect the average moisture level of the material between its surface and the electric field s maximum penetration of 3 4 in Moisture closer to the surface has a greater effect on the reading than moisture at the maximum penetration depth TOT MMD5NP Manual FINAL 051811 Laygyt1 5 18 11 11 12 AM Page 4 The MMD5NP has been calibrated at the factory for use with wood and building material concrete bricks wallboard etc Because the capacitance of wood and the capacitance of building material are affected differently by moisture the meter measures their moisture content on different scales A button on the front of the MMD5NP provides a convenient way
