How to test for ground loop using multimeter?
I am experiencing a hum in my audio line from my computer. I suspect it’s from a ground loop. My monitor (which house the speakers) is a 2 prong plug is plugged into a separate outlet from the power strip of which the PC is plugged into. I thought this prevents a ground loop but I would still like to test.
I just got a multimeter, and I have no idea how to use it. All the examples I see on ground loop testing are not for PC/Monitor jacks.
Can anyone give me a step by step. I have this multimeter: http://www.amazon.com/Sinometer-Manual-Digital-Multimeter-MS8268/dp/B000JQ4O2U?SubscriptionId=02B7Y8VZ2ZRE5MXHPMR2&tag=vglnk-c1001-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B000JQ4O2U
