I only had a brief introduction to the oscilloscope when I was in college. Can someone describe the capabilities/value of an oscilloscope when troubleshooting building circuits? I do quite a bit of troubleshooting and have always managed with a Wiggy, receptacle tester, Amprobe, multimeter, continuity tester, tone and tic tracer. What other circuit tracing equipment do you use to make troubleshooting and tracing building wiring faster?
Mate, you need to understand what a "scope" is used for.
Pretty much, if you've been told that they can do any more than measure voltages/currents versus time, you have been lied to.
As that is inherently what an oscilloscope does.
I own two 'scopes, one is a cheap DSE model that is only good for a ball-park idea, the other is a Tek-tronix model that I've owned for 25 years.
You can't merely bank large voltages onto the input of a 'scope, this will kill it, no matter what attenuation you have on your probe.
I don't think personally that a 'scope is a bit of test gear that an Electrician needs, unless they are doing Industrial problem solving.
Drop an old school CRT scope and you've pretty much got a box of broken glass.
