<DIV>Good point.</DIV>
<DIV> </DIV>
<DIV>For my use (making comparisons) the RS meter is fine. The club I formerly belonged to also used them for enforcing a club-imposed noise limit.</DIV>
<DIV> </DIV>
<DIV>However, if it comes down to enforcing a local noise ordinance, a calibrated meter traceable to NIST would probably be required. I'm not sure, but I don't see why you would not be able to have a RS meter calibrated, although I am sure the measurement uncertainty would not be very good. I'm sure the calibration would probably cost more than the RS meter.</DIV>

<DIV>What are/were the circumstances of "needed in a court of law" are you referring to?</DIV>
