Cam and crankshaft sensor
I would like to know to properly use my U Scope to measure the 5 volt square wave pattern on a camshaft sensor. I am able to get readings on my U Scope when the engine will start and run. But I am having trouble getting a reading on a camshaft or crankshaft sensor during cranking.
I would be will to pay for training or purchase an material that might help me.
I am grateful to own this tool and want to learn to use the tool more effectively. I you would have any suggestions please let me know.

For this set your time to 100ms.
Once you get something, go to 50ms, then go as far as needed to analyze the waveform.
For more specific instructions, send us a photo or screen shot so we can see what you see.

The setting really depends on the car and how often the CAM signal occurs every revolution.
If it's a 1/2X signal, it only occurs once every 125ish ms.
So 1 second screen might be ok.
If it is a high resolution signal, then it may need to be set with a faster timebase to see the signature.
It's not a one size fits all type of thing.
