a logarithmic resolution[ millivolt /decade]
0000 = linearizing off
0001 = min. value
9999 = max. value
(default value: 0000 = linearizing off)
b full scale [millivolt]
0001 = min. value
9999 = max. value
(default value in logarithmic mode: 5324 = 5.324V)
(becomes linear full scale = 1000000)
Pressure control algorithm adaptive downstream needs a linear sensor signal, therefore a
logarithmic signal must be linearized.
Example: s:1700000000 = Linear sensor
Example: s:1810007800 = Logarithmic sensor (1.0V/decade, Linear full scale at 7.8V)

Remark: For pressure control averaging of sensor signal is not recommended.
This function does the sensor average configuration.
