In an earlier post you said "Series resonances, which mean 
the grid is
most effective, will show up on a GDO.">>

That's correct, because it is not a lunmped two compoennt 
network that is open circuited. It is more like a 
transmission line.

Your post above says the opposite. Did you mis-speak on one 
or the
other? >>

No I didn't. My giouess would be you are confusing measuring 
something that is two lumped componenst with a distributed 
system.

I'm not aware of any rule that says a GDO can't measure a 
series-resonant system. Are you? Are you actually trying to 
say a GDO can't measure a series resonant system?
