The device will, however, continue operating correctly for a certain time. the battery has been completely used up, if ´bAt´ is shown in the upper display. The battery has to be removed, when storing device above 50°C.

Choose between the individual values that can be set by pressing the "Menu"-key (key 4) again. The individual values are changed by pressing the keys "5" (key 2) or "6" (key 5). Use key "Store/↵ ↵" (key 6) to leave configuration and to store settings. 2.1 2.
H60.0.01.6C-11 Operating Manual GMH3810 page 5 of 14 Wet-Basis Moisture Content w (relative to total weight, mind the arrow at left bottom!) The wet-basis moisture content expresses the ratio of the mass of water to the total mass of the substance. The ratio is represented by the following equation (the unit is % as well): wet-basis moisture w[%] = (weightwet - weightdry) / weightwet *100 Or: wet-basis moisture w[%] = (weightwater) / weightwet *100 Example: 3.
H60.0.01.6C-11 Operating Manual GMH3810 page 6 of 14 Frequent sources of errors: - Attention with oven-dried wood: the moisture dispersion may be irregular, often in the core is more moisture than on the edge. - Surface-moisture: The wood-edge could be more humid than the core if the wood had been stored outside and e.g. was in rain. - Wood preservative and other treatment could falsify the measuring.
