+What: /sys/bus/iio/devices/iio:deviceX/in_resistance_calibbias
+Date: August 2021
+KernelVersion: 5.15
+Contact: Andreas Klinger <ak@it-klinger.de>
+Description:
+ Set the bias value for the resistance which is used for
+ calculation of in_concentration_input as follows:
+
+ x = (in_resistance_raw - in_resistance_calibbias) * 0.65
+
+ in_concentration_input = 500 / (1 + e^x)
+
+ Default value: 30000
