Hi thanks for this
A DVM should be able to, the signal is from 1.5 to about 5V DC at around 30Hz (Incorrect terminology, this should be CPS) a DVM should see up to about 1kHz. These are TTL levels so I assume that a logic probe will see it too, just need a +5V ref! (I don't have a CRO or a logic probe laying around, but I do have a DVM and some electrical nouce)
As it is a Hall sensor, it remains excited while in the magnetic fiel. I should be able to trun the engine over and see +5 and near 0V as the shutter wheel moves through the sensor, or at least that is my reading from this information
I will check my thoughts, but it looks like I am up for one of them expensive sensors och!
Again, thanks
