Gain [G]
[G] defines the volts / user unit, for example, V/m. WXT reports the voltage at input multiplied with the gain [G].
For example, if the sensor has gain 2 V/meter and the user sets the gain [G] to 0.5, the value reported by WXT is in meters. WXT reports the value with 6 decimals.
The range: 0.000 000 001 … 1 000 000
Parameter selection [aIU,R= (bit 3 and bit 11)]
