  23 Description:
  24                 Set the bias value for the resistance which is used for
  25                 calculation of in_concentration_input as follows:
  26
  27                 x = (in_resistance_raw - in_resistance_calibbias) * 0.65
  28
  29                 in_concentration_input = 500 / (1 + e^x)
