Application notes
measuring point, the veneer is
remaining stack (avoid friction: electrostatic charge!). Any wood
particles adhering to the measuring surface must be regularly
removed. If the elastic, plastic measurement sensors are damaged,
they can be reordered (no. 4316) and glued on using standard
cyanate-based instant adhesive.

Push-in electrode M 19
The electrode is used for measuring in finished thermal insulation
composite systems. It is possible to measure even in plastered
insulation boards by purchasing insulated electrode pins.
4.1.1.4
M 20-HW 200/300 stick-in electrode pair
If the hex nuts with standard electrode pins on the M 20 electrode
are removed, they can be replaced with the M 20-HW electrode
pins. These must be fastened tightly!
For measurements in shavings and wood wool, it is advisable to
compact the material to be measured a little. To do so, wood
shavings should be pressed together with a weight of approx. 5 kg.
No compression is necessary for balls of wood wool.
4.1.1.5
Ram-in electrode M 18
Both needles of the ram-in electrode are to be hammered to the
required measurement depth at right angles to the grain direction
with the slide hammer. To determine the core moisture content, the
electrode pins must reach to between 1/4 and 1/3 of the overall
wood thickness.
Pulling out the needles is also done with the slide hammer with the
impact direction upwards. Where possible, the hex nuts should be
tightened with a spanner or pliers before beginning a measurement
sequence. Loose electrode pins break easily.
