Dayton EMM-6 cal files are wrong
The Dayton EMM-6 measurement mic is a great deal at $50 but the calibration files they are supplying are very inaccurate. I had the mic calibration verified by a third party and the Parts Express calibration measurement is way off. Don't use it. The extreme wiggles are measurement artifacts and the flatness of the extension at the frequency extremes is completely incorrect. The first attachment is the PE measurement. The second is the third party calibration.

Your mic is a lot closer to flat than mine (enclosed cal files were similarily out-to-lunch)
