Zero Adjust Mode
The CDG Sensor is adjusted automatically by the Pirani sensor, if this index is set.
The High Trip Point is calculated by:
High Trip Point = Value
*)
× Percentage
**)
*)
Value from Piezo Sensor (I: 0x6010, SI: 0x11)
**)
Percentage
High Trip Source (I: 0x800E/F, SI: 0x13)
In this case, the High Trip Point value is automatically updated by the device itself.
Any user-written value to the parameter High Trip will be refused with an abort
code.
The Low Trip Point is a fixed value:
The value defined in Low Trip Point Limit is compared with the pressure value
referenced by the Source Index parameter.
