Have you tried to look at all signals with a reasonably fast digital scope, setting the scope to trig for signals outside the normal range? Sometimes the additional connection to a scope (with its separate connection to protective earth!) can add a new set of problems. At least, when measuring mains related stuff. Ideal here would be the use of a battery powered scope. Been there, done that. I previously used a Fluke ScopeMeter, but have now switched to using a laptop (running on batteries) with a USB-operated PicoScope. Alas, I find the PicoScope software seriously lousy - many of the simpler USB scopes have way better software. |
