Wet/dry LED indicator
In addition to numeric measurement display in % of relative material moisture, the LED display also
provides a material-dependent evaluation of moisture. The LED display bar becomes larger, from left to
right, with increasing moisture content. The 12-position LED display is subdivided into 4 green (dry),
3 yellow (moist) and 5 red (wet) segments. Wet material causes an additional acoustic signal.
Green = dry
!
The classification „dry" means that materials in a heated room have reached a balanced moisture
level and are thus suitable for further processing.

Setting the wet/dry threshold values in index mode
The wet/dry LED indicator is programmed in line with the relevant material characteristics so the LEDs also
provide information about whether the material should be classified as dry, moist or wet. However the
values in index mode, which is independent of the material type, are output on a neutral scale whose value
increases as the moisture level rises. The LED indicator can be specifically programmed for index mode by
defining the end values for "dry" and "wet". The difference between the value set for "dry" and that set
for "wet" is converted and displayed by the 12 LEDs.

Material temperature compensation (for wood only)
Relative material moisture is dependent on the temperature of the material. The device automatically com-
pensates different material temperatures in that it measures ambient temperature and uses this measure-
ment for its internal calculation. However, the measuring device also offers an option for setting the
temperature manually to increase measuring accuracy. This value is not stored and must be set again
each time the device is switched on.
