are Shift_method = 0 and Offset = 000 in SM_config. Any other setup using Shift_method = 0 combined with Offset ≠ 000 leads to erroneous

analog setups.

The setting for ADC resolution for the external sensor (bridge or voltage-source sensor) affects the typical measurement duration and noise

See section 3.2 for definitions of measurement types AZSM, SM, AZTM, and TM.
