Thank you for your interest in our products and for contributing to our community.

There are two ways to change the offset of an ADC instance.

1. With User Offset in Config Tools, as the image you have shared.
2. In code, using Adc_Sar_Ip_SetUserGainAndOffset() function.

See details in User Manual for S32K3_S32M27x ADC Driver in right top corner of ADC driver:
