Ive look in the help section and nothing about overlay, how do i do it ?

Thanks

Thanks for pionting that out Kev, it's pretty obvious when we think about it, Ive should have know that, for for example when the end fall off the pressure washer I can hear the pump change tone because it not working so hard, I so wish I wasnt so much of a Div

Thanks Again

Dont know Mate, Ive just looked at the waveform and belive me I am no expert, Ive not even put the batteries in me Pico current clamps yet. EDITED, didnt want to look more of a Div than what I already am !!!!!!!!!! I would have thought if the old pump was working harder to deliver the fuel it would ...

Yep sorry, found it, its set at 200ms/div !!

Thanks

Ive not changed any sample rate's, thats the default 12.0 bits, I'll paly with that later !!!

Thanks for the help guy's, all the scopes Ive had over the years have never had a filter, they've just displayed a line so that through me a bit

Thanks

So would the filter work on say this waveform:

of MAF that Gruss posted,

Sorry for all the question, Im have been using various scopes over the years and never seen a waveform like these, they have all been just a line

Thanks guys the filter has done the job

Hi All used my scope today for the 1st time wanted to check MAP and o2 sensor but having a small problem with display, as you can see I cant get a nice neat fine line, blue trace MAP, red trace o2, what am I doing wrong ?

Thanks for the info, I'm on the bonnet side

Thanks
