[V6-12v] Ox sensor duty cycle

[Tom Christiansen]

Mike,

You didn't mention the sampling rate of your data logger. If it's really 
low (> 0.5 Hz) you will have trouble reading the signal from the O2 sensor. 
In that case you get aliasing which may look like you describe. The 
sampling rate should be at least 2.2x the max signal frequency.
