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.
