Re: Old frequency meter

it goes across the line like a volt meter - but check the voltage - they
have the specs printed on them. I'd suggest you don't waste the panel space
on it, only the 60 hz reed will ever vibrate when powered off the mains -
where it's handy is if you have a motor powered generator and you want to
get the freq right.
