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.
