6.0 MOST COMMON REASONS FOR MEASURING ERRORS
 Product temperature beyond ambient conditions: The temperature of the
measuring device and of the product should be nearly equal.
 Wrong switch position
 Uneven pressing
 Wrong application on rolls
Press your measuring device lengthwise to the longitudinal axis of the
product roll, otherwise the bearing area of the sensor is too small.
 Product pile not thick enough
 Electrically conductive material
All metallic objects as well as electrically conductive packaging film or paper
coloured with carbon black influence the measuring result in a negative way
and must no be positioned within a range of 500 mm below the sensor area.
 Exceeding of measuring range:
This can occur depending on the type of product and the position of the
selector switch. It is indicated on the display by blinking and means that the
measuring accuracy is less precise.
