3.2.9 Amplifier Configuration and Level Shift.
support a Level Shift value, such as the Thermocouple Sensor. It is used to
determine at what amplifier stage the Level Shift effects the computations.
Different boards use different types of configuration such as Nonlinear/Difference
or Instrumentation/Difference.
