Generator Check using Portable Power Protection Unit

I use a fluke multimeter to check the frequency of the genny ac power- it is within a few cycles of 60 Hz all the time under various loads.
Like the voltage it will swing slightly as the Onan 2800 responds to load.

A more likely source of problems is shore power- easy to check with a plug in "checker" along with a voltmeter.

Good practice to check before plugging in.


this way you know what is happening, rather then using a "box".
keeps money in your pocket too.
