Oxygen Sensor / Lambda sensor reading problem

Post by nickyy » Thu Jun 12, 2014 7:23 pm

What are the recommended Picoscope settings & test lead configs for testing oxygen sensors?
I've set the software to: 500ms/div, x1, 1v and I don't get the nice waveform. (I've tried this on several sensors).
I connect a red lead to the black wire (4-wire sensor) and the black lead (connected to the red lead's Y) to the grey wire.
I suspect I am not connecting the leads correctly.

I am guessing you have one of our automotive scopes and are running the automotive software, therefore I would suggest posting this request on our Automotive Specialists forum http://www.picoauto.com/support/

adding a psdata file showing what you have captured would also help, File->SaveAs and just save the Current Waveform.
