When measuring moisture contents in narrow pieces of wood you can do it along the fibers For moisture contents over 20 the result will be a little bit higher than the real moisture contents Results below 20 will not be noticeably influenced by the direction of the measurement e Wood Moisture Meter PCE WMHG is an electronic device The components used for production of PCE WMH3 guarantee its reliable and long operation The part that is most often subject to accidental damage is the LCD Please pay special attention not to damage the LCD during the measurements f When a needle breaks use a small screwdriver to unscrew the broken part of the needle or remove the plastic part unscrew the bolts with the springs and unscrew the broken needles from the inside 11 Storage Store the device in a chemically neutral atmosphere In temperature 5 C to 40 C and relative humidity 2096 70 RH If the electronic circuits become moist dry the whole device Unscrew the plastic part with the needles and heat the device up to 40 50 C not more The drying should last at least a few hours For example you can put the device on a radiator 12 Exotic wood types Group 1 set WOOD TYPE to 1 Chipboard phenolic resin bonded Gonzales Alves Parana Pine Zebrano Group 2 set WOOD TYPE to 2 Assegai Avodir Box tree Brazilian rosewood Chipboard urea bonded Cedar white red Cocuswood Columbian
