If a measurement should produce no change of the LEDs, it
is possible that the measured material is too dry. Perform a
self-test of the device with the protective cap to make sure
the device is in good working order.

If a measurement for a group B wood is now made, the material‘s
moisture in % will be displayed in the lower scale. In this case, the
right-most illuminated LED (regardless of colour) and the colour-scale
beneath it are used to determine if the wood is to be classied as „dry“,
„moist“ or „wet“. Evaluation is now based on the lower colour scale.
Green = dry, yellow = moist, red = wet.
Example shown: 23%, red section of the lower scale = wet.

After switching the device on, all 12 LEDs will illuminate briey.
Thereafter, the rst green LED will blink continuously. The device is
now ready to use. If a measurement for a group A wood is made, the
material‘s moisture in % will be displayed in the upper scale. 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. The moisture content of
wood can be determined both from the percentage gure as well as
from the LED colour. Example shown: 13%, green LED = dry.

The location to be measured should
be untreated, free of knots, dirt and
resin. Measurements should not be
made on the end faces of wood
because these areas dry particularly
quickly such that they produce
incorrect measurement results.
