1.0 POSITIONING THE INSTRUMENT

Insert the sword-sensor into the stack for only approx. 10 cm, and push it a few
more centimetres into the stack every 10 seconds. Let your RH6 adequately adjust
to the material (at least 5 minutes) before you start to measure, particularly when
the material pile was stored at a different temperature than the device. When
removing the sword-shaped sensor please ensure that there is no up or down
movement, because this could deform the sensor. For heavy stacks and rolls please
use the optionally available sword sensor holder and the tool for removing the sword
sensor holder.

1.1 Measurement

To switch on the instrument, press the

key for 3

seconds.
After showing the logo, the measuring window opens and

the current temperature and moisture value is displayed.
In the type selection menu the calibration curves can be

changed by pressing

or . The calibration curves saved

in the device can be found in the following list.

3.0 DESCRIPTION OF DEFINITIONS

Relative air humidity: indicates the relation between the current water vapour

pressure and the maximal possible water vapour pressure (called saturation vapour
pressure).

The relative humidity shows the degree the air is saturated with water vapour. For
example:

50% relative humidity indicates that at the current temperature and the current
pressure the air is saturated with water vapour for half of its value, 100 % relative
humidity means that the air is totally saturated. When the air has more than 100 %
of relative humidity, the excessive moisture would condense or form fog.

Absolute humidity: shows the contained amount of water in gramme per cubic
metre of air. The absolute humidity is a direct degree for the amount of water vapour
contained in a certain air volume. It shows how much moisture can maximally
condense or how much water has to be evaporated to receive a certain desired air
humidity.

Dew point temperature: The dew point indicates the temperature that the not
completely saturated air has to reach in order to be completely saturated with water
vapour. If the room with the current relative humidity is cooled down to the dew point
temperature, the water vapour begins to condense.

EMC wood: shows the equilibrium moisture content of wood (for timber stored
under these conditions) in % moisture content of wood and the temperature in the
selected unit (°C or °F).

aH kraftliner: shows the equilibrium moisture content of kraftiner paper (for paper
stored under these conditions) in % moisture content and the temperature in the
selected unit (°C or °F).

aH testliner: shows the equilibrium moisture content of testliner paper (for paper
stored under these conditions) in % moisture content and the temperature in the
selected unit (°C or °F).

empty curves: can be used to calibrate some special products

4.0 APPLICATION RANGE

Within the normal application range (normal range) the accuracy of the device is as
indicated. A long-term application beyond the normal application range (max.
range), particularly at an air humidity of more than 80%, can lead to higher
measuring errors (+3% after 60 hours). Back in the normal application range, the
sensor will return to the indicated accuracy automatically.
