WIKA Additional Instructions Pressure Transmitter with CANopen Interface D-20-9 / D-21-9 37
Input Offset
6124h AI_Input_Offset
For manual offset correction the detected offset is sent to the device, e.g. the device (pressure range 10 bar /
1,000,000 Pa) indicates 0.01 bar / 10,000 Pa at ambient pressure.
The user writes the determined offset to object 6124h subindex 1 (AI_Input_Offset_1),
i.e. in this example 10,000 Pa (=> 00 00 27 10 h)

Changed parameters are not automatically stored, but they have to be stored via object 1010h Store
Parameters.
Furthermore the device can be reset to the factory settings via object 1011h Restore Default Parameters.
Input Autozero
6125h AI_Input_Autozero
The zero (pressure = 0) is changed to the actual pressure.
