I dragged out Wayne's scope and a few meters to debunk a myth about
propane.
Someone was trying to tell me the output was less on propane than on
gasoline. I will admit it uses about 50% more by volume but for the
same output.
I used my convection oven for a load and that ended up being 5403
watts or around 98% of the rated output of the generator, a pretty
good test.
The wave form ended up being pretty "siney" although not perfect and
did not change with the fuel

The rest of the test looked the same too.

I have that scope ready to go any time you want to drive to Estero
Wayne. For being 50 years old, it is still working pretty good.



The "output" won't be less on propane but the efficiency is.

Your pic makes me want to go track down the guy I lent my HP scope to. :-)
