Is it possible to change the grid and trace colours with Picoscope R6?

Thanks for the info and downloads.

It's interesting what you say about the floating ground of an oxygen sensor. I checked my hand held scope and there was no shift of DC with scope ground connected to battery ground or oxygen sensor ground. Pico states in their installation guide (Page 5) "Take care to avoid connecting ground input o...

I connected my hand held scope ground to the oxygen sensor ground with only a slight increase in frequency.(Results not downloadable). Here is another psd file showing the same Renault Clio at fast idle (2000 rpm). I was somewhat surprised to see the frequency still above 1Hz and the DC at the same ...

What is the correct ground connection for an oxygen sensor test? Battery ground or sensor signal return. On my Renault Clio (4 wire sensor) the signal return has a small reading above 0v so I opted for the battery ground. The results are attached. I thought the frequency was rather sluggish and also...

Many thanks for the waveform.

Thank you for that reply. Has anyone any 212/3 waveforms to show whilst the FL Sensor is connected directly to the inlet manifold with the engine idling?

Can the FLS connect directly to the inlet manifold (brake servo connection or similar)whilst the engine is running?
