Self test
Go to TEST mode by pressing and releasing the MODE key. Place the electrodes at the contacts
on the protective cap, marked with "T" and "B". Compare the display with the following pictures.

Measurement of the ambient temperature and air humidity
The universal moisture meter continuously measures the ambient temperature and relative
humidity. The ambient temperature is used for temperature compensation during material
moisture measurement, thus increasing the accuracy. Press and hold the [SET] key for 2 seconds
to toggle the display between ambient temperature and relative humidity.

Moisture measurement
Before starting the measurement, you must first select the material group by briefly pressing the
[MODE] key.
WOOD for measurements in wood, wood-based materials and cardboard / paper, divided into
3 groups
BUILD for building materials such as plaster, aerated concrete, screed and concrete, divided
into 4 groups
TEST
to check the meter with the supplied protective cap
Then select the wood or building material group as described in the following sections 7.1 and
7.2. To measure the moisture content, slowly and carefully prick the measuring electrodes into
the material (without applying much force). The puncture in wood should be vertical to the wood
fibres. At a moisture content of less than 20 %, the penetration geometry is of no great
importance for the measurement result. Always measure at several points for comparison or to
be able to calculate an average value.
For hard woods and building materials, the use of ram electrodes is recommended. These are
connected to the plug on the protective cap via the connection cable. The paper electrode is
connected in the same way. For very hard material, where there is a risk of destroying the meter
(breakage of the needles), it is also possible to drive in two nails and apply the electrodes to
these.
