    Just re-measured with the Fluke and one cheap meter side-by-each.

    129v peak measured 125v RMS on the Fluke.  264v peak was 249 RMS ( 6% 
error ).  Still high, but not enough to cause any problems, I don't think. 
I didn't think the difference would be that large.  File under, "cheap 
tools" and "you pay for what you get".

    Thanks.
