Default Onan Meter Panel

A friend of mine gave me 3 meters he had laying around in his shop.

He gave me a AC Volt meter, a Hertz meter, and a Percent Rated Current meter.

He said they were out of a military type Onan generator. I would like to make a panel for my 6.5 NH that I have at my Camp.

Can I hook these up to a 120 side and get readings, or is something else needed?

I will get some pics of the meters up soon.

Check them over real good. They may be DC meters. I have seen some where the military converted AC to DC to run the panel meters. Why I don't know

Can you post photos, chances are the load meter will be useless unless you have the CT transformer to go with it, if the frequency meter is of the vibrating reed type you can probably use it if it is the right voltage for you, and if it has a needle chances are it is one that connects to a frequency transducer, without the transducer it is useless. The voltage meter should be a direct connect item though.

This is making assumptions having not seen the photos.

Military probably converted to DC panel meters either because they had them in stock for something else or they were cheaper.

Meter #1, HZ, is a DC meter. FS=200uaDC. Full Scale = 200 micro amp DC

Meter #2, Percent Rated Current, is an AC meter used with a current transformer. FS=1AAC Full Scale = 1 Amp AC

Meter #3 is an AC voltmeter

So the only one that I could use is the Volt meter?

Can a Current Transformer be bought and put in line, or should I just not pursue it?

Thanks!

The frequency meter is useless for your purposes.

The percent current meter could be used with a current transformer, but because the calibration is "percent rated current", you would at least have to make a new scale for it.

The AC voltmeter can be used as is.
