Special functions
Special functions that are available are described in the Operating Instructions pertaining to
the device.

Diagnostics and troubleshooting
The device is normally precalibrated with calibration set B and Cal.14 (air/water 0 to 100 %)
upon delivery.
Fine-tuning to achieve an accuracy of ±0.1 % in relation to the laboratory value can be
performed via a PLC or the remote display (optional).
Fine-tuning with the PLC
Depending on the PLC, it is possible to perform a parallel shift/offset in the PLC. The
parameter has different names depending on the PLC (e.g. initial load, zero point, offset,
measuring range, etc.).

Different moisture value
If the moisture value of the device deviates by more than ±1 % from the laboratory value
during initial commissioning, this may be due to the following:
Incorrect installation in the material flow
The measurement surface must be sufficiently covered. A good, stable flow of material must
be guaranteed.
‣
Correct the installation or material flow
A video of the material flow during the batch process can be helpful for analysis
purposes.
The wrong calibration curve is set
The device is delivered with calibration curve Cal.14 (air / water 0 to 100 %).
‣
Select a suitable calibration curve.
