Here we have a great article online by LMH Engineering Services Ltd. This article is based upon the Running Compression waveform that is produced when using the PicoScope Automotive Oscilloscope and the WPS500X Pressure Transducer.
View the Understanding Running Compression article on the LMH Engineeringwebsite.
Here we have a 30 minute video on YouTube with ScannerDanner. If you have seen Paul's videos before you will know their value, and that it is worth taking the time to watch them.
In this video Paul has been asked to diagnose this vehicle by another garage, and covers another variable when it comes to relative compression testing with a scope.

Q. I recently purchased a 4-channel scope. I would like to be able to overlay a captured waveform with a reference waveform. I can't seem to be able to find any information anywhere about how to do this. Please can you help? Thank you.
A. Yes this is possible. To do this:
The waveform is now loaded in the background. You can drag the vertical axis of either scale and separate or line up the two waveforms. It is worth noting that within the Reference Waveforms options, you can double click your "Available" waveform and rename it. If you do this, it is worth (with it highlighted) choosing "Export". Your reference waveform is then stored in: "....\My Documents\Waveforms\References". Each time you do this a ".psreference" file will appear here, slowly building your own library of Reference Waveforms.
As you build your own library you can then use the "import" option in the Waveform References to use them over and over.
Q. I am forever moving the axis of channels that "get in the way" of other information I want to look at. I want to keep the signal data from these channels, but I need to hide them at times, is this possible?
A. Yes this is possible. To do this simply choose Views>Channels. You will see a list of your active channels, each with a small tick beside them. You can remove/add this tick to hide/show individual channel data. The list of channels is also accessible via the right mouse click on the waveform data.
1) Load the file you want to compare to.
2) Choose Tools>Reference Waveforms.
3) If you have various channels enabled on your waveform, ensure that under "Available" you have the Channel you want as the reference highlighted. Choose "Duplicate". This waveform is now in the "Library" section. Click OK.
4) Now, use File>Open and open the second waveform that you want to compare to your first.
5) With this file open, again go to "Tools>Reference Waveforms".
6) You should see your previous waveform still located under "Library". Enable the tick box here and choose OK.
