/ AcoustiCal AcoustiCal Models The 3M AcoustiCal AC-300 is an acoustic calibrator for calibrating precision Class/Type 1 as well as general purpose Class/Type 2 sound level meters and noise dosimeters. The AC-300 produces two signals either 250 Hz or 1000 Hz at a sound pressure level of 114.0 dB. -
Page 5: Battery
Battery Battery A 9-volt battery is used to supply power to the calibrator. Low Battery At a low battery condition, the low battery indicator will appear. If the battery level becomes too low, the calibrator will power off. Changing the battery The battery door is located on the top of the calibrator. -
Page 6: Performing A Calibration
Performing a calibration Performing a calibration A microphone is sensitive to temperature and pressure changes. Calibrating before taking measurements assures that your level measurements are accurate for the current environment; and performing a calibration after use allows you to verify the integrity of both the calibrator and the sound level meter. -
Page 7: Factory Service On The Calibrator
3M Quest Technologies recommends checking the performance and precision of your calibrator on an annual basis by sending it to a factory-authorized service center. The AcoustiCal is calibrated at Quest Technologies laboratory, a 3M company, with a Type L standard microphone and with special instrumentation traceable to NIST. The calibrators are very stable;... -
