Reading off the measured values
The moisture content is given by the measured value display in
the centre of the display screen. In order that values can be read
off easily, the measured value display takes the form of bars that
are alternately continuous and subdivided.
An arrowhead at the left-hand or right-hand end of these bars
corresponds to the exact read-off value on the dampness scale,
in the direction to which it points.
Bars without arrows correspond to intermediate values on the
dampness scale in question.
The read-off values on the left-hand dampness scale are used
for wood moisture measurements. The instrument records wood
moisture values in the range from 6 to 44 %.
The read-off values on the right-hand dampness scale are used for
building moisture measurements. The instrument records building
moisture values in the range from 0.2 to 2.0 %.
If measured values lie above the range of measurements that
can be recorded, the measured value display shows, as a warning,
a large triangle at the upper end of the bars that are displayed over
the valid range of measurements. Measured values outside the
range of measurement are not meaningful.
