2.0 SELECTION OF CALIBRATION CURVE

Due to the countless number of paper types there is no standardised allocation of
calibration curves. The different calibration curves refer to the different densities of
paper or paper rolls.

The list of calibration curves below shows suggestions for paper types.
To ensure the best accuracy of your measurement you have to carry out a

comparison measurement using your online moisture measuring system or by kiln­drying (according to DIN 287) once.

1. Measure the water content of your paper (on the roll or the pile) using all
calibration curves that offer realistic results and write down the measuring
results of the different calibration curves.

2. Now please note the effective water content determined by your online
measurement system or carry out a reference measurement according to EN
ISO 287.

3. Compare the determined reference water content with the measuring results of
the different calibration curves. Use the calibration curve with the measuring
result nearest to the reference water content. Info: The name of the calibration

curve can be modified to your specific paper name!

3.0 DETERMINATION OF THE REFERENCE WATER CONTENT

The humimeter PM3 determines the water content, which means that it calculates
the moisture referred to the total mass (EN ISO 287):

WG

MtMn

100% ×

Mn: Mass of the sample before drying
Mt: Mass of the dried sample

reference

The back side of the humimeter PM4 contains
an embedded temperature sensor for the
contact-free temperature measurement below
the sensor. This ensures the determination of
the temperature of the product within seconds
and consequently the temperature
compensation of the displayed water content.
The sensor must not be covered by a hand or
any other object!

window for approx. 3 seconds a list of all available
calibration curves opens. Now you can select your
desired curve using the arrow keys and confirm by
pressing

.

17.0 COMMON REASONS FOR INCORRECT MEASUREMENTS

• Wrong calibration curve
Double-check the correct selection of the calibration curve before measuring.
The calibration curve „reference“ must NOT be used.

• Inadequate thickness of the paper pile

A single sheet of paper must NOT be measured. Make sure that the paper pile

below the steel clamps has a thickness of at least 100 mm.

• Electro conductive material

Every metallic object as well as electro conductive packing material e.g. paper

coloured by soot or wire has a negative effect on the accuracy of your
measurement. Make sure that in an area of 20 cm below the sensor steel
clamps there is no such material.

• Product temperature out of application range

The application range is between 0 and +60°C.

• Discrepancy in temperature between device and material

Please ensure that the device and the material under test are being stored at

nearly the same temperature before measuring. A high temperature difference
has a negative effect on the stability of the measurement results.

• Measurement at the front side

A measurement at the front side of a paper roll will bring different measuring

results. For that you have to select a different calibration curve.

• Bended steel clamps

If the steel clamps (measuring area) are bended you might get wrong measuring

results.

Please note:

• After measuring at the running paper roll for a longer period the steel clamps will
get hot – don´t touch! => risk of getting burned!

• Measuring fine paper at the running roll may cause pressure marks on the paper
=> for possible damages at the paper we refuse any liability.
