X1 = Signal Range Min (Electrical input from Sensor)
X2 = Signal Range Max (Electrical input from Sensor)
Y1 = Gas Range Min
Y2 = Gas Range Max
Gas concentration (y) is calculated as follows:
y = (((Y2-Y1)/(X2-X1))*(x-X1))+Y1
Note: Signal Range Min and Max are over-written during
calibration, and are then no longer editable
