• In the case of materials where the slope does not roughly correspond to a calibration curve
saved in the sensor, a 2-point calibration (dry and wet material sample) may be necessary
in the PLC or sensor.

• In the case of coarse-grained or hydrophobic materials, water can escape directly onto the
measuring cell and therefore cause a high moisture value. In this case, limits must be
entered in the PLC.
Please contact the PLC manufacturer for more information.
• Due to inaccurate data processing, it may be necessary to check the moisture value
displayed in the PLC. For this purpose, connect the sensor to the remote display and check/
compare the moisture value shown in the PLC with the moisture value shown on the
display.
Caution:
The
"CA"
operating mode in the sensor must then be set to the
"CS"
mode for a test run, and
then switched back to
"CA"
again afterwards.
• Check the start/stop conditions in the PLC
• Start condition: time in seconds or kg in the scales
• Stop condition: usually % of target weight
• Please contact the PLC manufacturer for more information
If the solutions outlined here do not rectify the problem → contact the manufacturer's
Service Department.
