Yes....all 8 need to be viewed to help understand how an event on the utility or premise electrical system affects the monitored points. Using a couple 4 channel Fluke 190 scopes and/or a Dataq DI 718B data logger. Thanks.

Thanks for the response Dean. I know I didn't provide all the information as to my setup as it would take several pages. I do believe my question was answered by JimB as I was mostly hoping for verification of my thoughts which I received.
Certainly I would move the scope to the point of...
I appreciate the information! In the situation I'm working on the points need to be simutaneously measured to verify if any events affect them together or separately, and they are all separated by 100 feet or more. Also, I'm trying to verify if readings taken by another party are valid so I'm...
Extend scope leads
Thanks for the explanations and diagrams. This is how I would expect the connections to be made. I thought I would check as the person who's readings I need to check wired the extended probes "backwards".

Trying to measure anything that is there. I would expect to measure a half a volt 60 cycle. I'm guessing this 60 cycle might appear modulated if there are electonic ballasts or variable frequency drives in the building.
Yes, you have a good question: Typically when measuring for 60 hz AC voltage using an RMS Voltmeter from earth to equipment that is connected to the electrical system you might pick up a few tenths of a volt or so because of normal voltage drop on the premise electrical system. I am expecting...
I would like to verify measurements taken by another person with a Fluke Scopemeter and would appreciate some feedback. Measurements were taken at various outdoor points such as a well casing and metal tin of a building to see if there was any voltage/frequency present.
Here is how it was...
