9.2.5 Corrosion monitoring
Sensor connection cable corrosion can lead to false measured value readings. Therefore
the unit offers the possibility of detecting corrosion before a measured value is affected.
Corrosion monitoring is only possible for RTDs with a 4-wire connection and
thermocouples.
2 different levels can be selected in the CORROSION_DETECTION parameter (see Section
11) depending on the application requirements:
