Figure 17 illustrates the procedure for testing the
effects of excess voltage applied to the heater. Heater
resistance was measured while the heater was
unpowered and at room temperature.
effects of excess voltage applied to the heater. Heater
resistance was measured while the heater was
unpowered and at room temperature.
The results of this test are shown in Figure 18 which
shows the change in resistance of the heater when
various heater voltages (rather than the standard
5.0V) are applied in the absence of gases.
shows the change in resistance of the heater when

As this section demonstrates, the heater shows good
durability against increased heater voltage.
However, since excessive heater voltage will cause
the sensor’s heater resistance to drift upwards,
excessive heater voltage should still be avoided.
