Dave,
I can see were I made it sound like I thought I still have a pure sine wave thats not what I meant. What I was actually trying to say was what you just stated that because it was not a pure sine wave if I took thousands of readings and averaged those it would work.

I'm looking at the document I saw that link in the email but it came acrossed somewhat broken I did not get the entire link as a complete link in the email.

Thanks
David
