I have a generator 7500 generac. How do i check sign wave, what do i
need, What is sign wave and what is good sign and how can it damage
electronics.
Do look at the sine wave your going to need an oscilloscope. That is really
not necessary for the average guy. Because the sine wave looks different
during different loads and situations.
Get a meter (volt, ohm meter some times called a Vom) that reads hertz and
set the gen set with 20-50% load to 60 hz and you will be fine assuming that
your on North America. Europe is mostly 50hz. This will be done with the
speed governer, check your manual for exactly how.
If the cycles are not close to what the electronics need then they can draw
more power. Clocks and items with clocks do not like hertz other that want
they expect.
