Dnk,
I've in the past, waited with a scope hooked up to a 400V supply(via an interface) waiting for an event to happen.
(Around the time that is supposed to happen I mean).
Sure a data-logger can only do so much, you have to be there for some aspects of the job.
But this is what I mean, us folks can be there long after all the workers go home and are tucked up in bed, the test equipment you use or the lack thereof, can mean the difference between getting that result or not getting it.
Data loggers can't do it all.
What I am talking about is Complex Test Equipment, not your everyday multimeter.
