Dead-band function

With the Dead-band function, you can freeze the AI reference for a defined area (that
is, dead-band) or ignore a low AI reference caused by possible electromagnetic
interference issues.
AI dead-band value = AI max (12.18/12.28)
In addition, 10% of the dead-band value is added as dead-band hysteresis positive
and negative. This value is internally set in the firmware and cannot be changed.
