Satzverständnis, s.u. "Extended inaccuracy of measurement" Explanation: For a definition of the term, see the following site, about half-way down P.8: http://www.havakalitesi.cevreorman.gov.tr/english/training_4... where it states: Combined and extended measuring uncertainties "We may compute the combines uncertainty from the uncertainty contributions of the calibration and the measuring of real samples. Calculations are done by an Excel sheet, using this formula:" If you think about it, there are indeed two factors in measuring uncertainty: the one being the uncertainty of the calibration accuracy of the instrument being used, and the second the presumably physical uncertainty of the action of measurement itself. -------------------------------------------------- Note added at 5 hrs (2008-10-23 09:14:48 GMT) -------------------------------------------------- Yes, der "Betrag der Differenz zwischen...." wird erhöht. |

Satzverständnis, s.u. s.u. Explanation: To me it sounds like the maximum frequency deviation is defined as the absolute value (+ or -) of the difference between the frequency of the sound pressure level from the sound calibrator and the nominal frequency *plus* the expanded measurement uncertainty. -------------------------------------------------- Note added at 5 hrs (2008-10-23 09:30:32 GMT) -------------------------------------------------- (absolute value of frequency difference) plus (uncertainty). |
