ABSTRACT:
According to the invention, a maximum output signal of the sensor is measured as the sensor is actuated and voltage is applied to its sensitive element to produce a prescribed heating temperature, whereupon one measures the steady-state output signal of the sensor and the duration of the transient process between the maximum signal and the steady-state signal.
