Description
Voltage signal of Sensor 1 after electronic
amplification (depends on gain).
Voltage signal of reference after electronic
amplification.
Voltage signal of Sensor 2 after electronic
amplification (depends on gain).
Ratio1/QO1 (Normalized ratio 1). Equals 1 when
no gas is present and goes down when gas is
introduced.
