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.

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

19.0 COMMON REASONS FOR INCORRECT MEASUREMENTS
Keypad symbols
• Sunlight or other sources of heat or cold that doesn´t correspond to the
surrounding temperature
• Dripping or sprayed water
• Irreversible damage of the sensor due to aggressive gases
• Danger of condensation because of changing temperature
• Polluted moisture sensor
• Foreign objects on the sensor
• Measuring errors due to too short conditioning
To demonstrate the importance of temperature adjustment, the table below shows
measuring errors due to a temperature difference of only 1°C / 1.8°F between the
measuring instrument and the substance to be measured at different ambient
temperatures.
10°C (50°F) 20°C (68°F) 30°C (86°F)
10%r.h. ±0,7% ±0,6% ±0,6%
50%r.h. ±3,5% ±3,2% ±3,0%
90%r.h. ±6,3% ±5,7% ±5,4%
At room temperature (20°C / 68°F) and assumed paper moisture value of 50% r.h. a
deviation of 1°C / 1.8°F between the measuring sens or and the substance to be
measured results in a measuring error of 3.2% r.h. A deviation of 3°C / 5.4°F would
result in a measuring error of over 10%.
Further examples can be found in the Mollier h-x diagram.

14.0 CARE INSTRUCTIONS
Do not drop the instrument or expose it to excessive temperatures. The instrument
is not waterproof. Do not immerse the sensor in liquid.
The intervals for checking the instrument depend on your operational demands and
the required level of accuracy. In general the drift of the sensor according to the
degree of use (constant humidity or use within the whole moisture measuring range)
is beneath 0.5 % per year. You can check RH6 instrument by yourself using the
calibration equipment (see optional accessories). For a fee, Checkline Europe can
also carry out a calibration at their factory. On demand you will also receive a
calibration certificate.

button two times to reach the menu point Options.
3. Enter the superuser password using the buttons resp. and confirm by
pressing
• The query “reset?” appears on the display.
4. Press the button for resetting the device to the factory calibration.
.
• The software reloads the factory calibration data and reboots the device.
This will need about 15 to 20 seconds.
5. Pressing the button you can exit without any changes.
13.0 CONDITIONING OF THE SENSOR
The conditioning of the sensor (time until the device shows the actual measuring
value) depends on several parameters. The parameter responsible for the highest
measuring error is a temperature discrepancy between the sensors resp. the whole
measuring instrument and the material to measure resp. the air. In order to fasten
the conditioning, the following proceedings are possible:
Spaced insertion of the sword sensor
o 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.
In case of a high temperature difference repeat this action – if necessary several
times!
o If you use the sword sensor holder, please ensure that both the sword sensor
and the sword sensor holder are adjusted to the surrounding temperature of the
material.
In this case insert the sword sensor holder at frequent intervals and leave the
sword sensor in the sword sensor holder for an appropriate period.
10.0 SINGLE-POINT ADJUSTMENT WITH 50% HUMIDITY STANDARD
For the adjustment the appropriate calibration equipment as well as calibration
ampoules resp. humidity standards of 50 % r.h. are required.
10.1 Proceedings
Preparation
To ensure as good as possible inspection results it is
essential that the measuring device, the calibration
equipment and the calibration ampoules have
approximately the same temperature. This
temperature has to be between 20°C and 26°C.
The best way to ensure the same temperature of the
different components is to store all components
together in a room with only small temperature
fluctuations minimum over night – better for 24 hours.
Components of calibration equipment
In this image you can see the components of the
calibration equipment and a calibration ampoule with
humidity standard.
10.2 Assembly of calibration equipment
1. Put in the first gasket ring in the upper part of the calibration device.
2. Push in the sword sensor in the upper part as shown in the picture.
3. Now put the second gasket ring into the upper part.
4. Lay in the textile pad in the bottom part of the calibration device, and pour the

8. Pick up the RH6 together with the calibration device STRAIGHT and DON´T
TURN IT AROUND. Screw it up like shown in the picture.
Then put the RH6 with the calibration device down on a table carefully and proceed
as follows:
Conditioning the sensor
To achieve best results, let the sensor adjust for two hours. The temperature has
to be between 20°C and 26°C.
If the shown measuring value differs more than the factory tolerance (1.5% r.h.), we
recommend to carry out a recalibration as follows.
