  Tony,
   Yeah, the Tenma brand (calibrator) from MCM is about $200.00 and doesn't fit every meter - just a few of the Tenma meters. For now I'm going to use my RS meter, keeping in mind the limitations. I'd rather spend the money on fuel at this point!

    John:

    Yes, it is very tricky.  The problem is finding the known reference.  That's why we have to re-calibrate so often even with a "quality" meter.  AMA told me at the time that the calibrator device itself was about $500.00...  Of course, it was designed specifically to fit over the mic of that particular brand of meter, and may not be very accurate with another meter unless a custom head was built to hold the calibrator exactly the same distance from the mic while blocking all outside noise sources...
