    I think he writes his own lines.... Perhaps he should hire someone!
    The week keyboard commandos don't bother me. They are more a source of entertainment. Just thankful I didn't wind up like them. Thanks for watching!

    Separate Diamond meters here. I don't need "absolute accuracy"

    Have never had the need to calibrate the Bird Watt meter.

    Hmm. So it’s not calibrated. Thanks!

    The bird watt meter is essentially composed of the meter movement and the the slug. Not sure if there's anything you can calibrate. Possibly because one slug doesn't cover the entire frequency range. I also have a Motorola watt meter, type S-1360, which uses a a rectangular plug in element. No calibration there either. These are on e-bay.

    Dennis,

    Read the links I provided....details are there re: plugs. They can go out of expected tolerance for the specified accuracy. We might call those “bad” and need replacement IF the owner wants to make the claim that “I’ve got a Bird and it doesn’t need calibrating.”

    73,
