The data for the User calibration (offset/gain) are located in the CoE in the group together with the other channel-specific setting data.

These data are also overwritten by a RestoreDefaultParameter (CoE 0x1011:01) or CompleteAccess access to 0x80n0.

From the FW revision specified above these two values are protected by an additional password in CoE 0xF009
