About this data addendum
This data addendum presents submission information for testing the 3M
TM
Sound Examiner SE-400 Series sound level meter
to the IEC61672-1 standard. The SE-400 Series is a data logging sound level meter.
Note: The nominal microphone sensitivity is -28 dB.
Linear operating range (sections: 5.5.10, 5.5.11, 9.2.7e, 9.3e, 9.3f)
The starting level for measuring level linearity is 114 dB at all frequencies. Calibration point is 114 dB at 400 mV @ 1 kHz.
Linear operating range with SPL A-Weighting and LEQ A-Weighting (sections: 5.5.10, 5.5.11, 9.2.7e, 9.3e, 9.3f)
Note: Reference level 114 dB, Cal Point: 400mVrms = 114 dB @ 1 kHz
