Select "A" Weighting for a general noise sound level, or "C"
Weighting for measuring high level noise. "C" Weighting is a standard

measurement of Peak Sound Pressure Level. If the "C" Weighted
level is much higher than the "A" Weighted level, then there will be a
largeamountoflow-frequencynoise.
4. Press the Hi/Lo button to select the appropriate range. If the noise
environment under test is between 30 to 100dB, use the 'Lo' range. If
the noise environment under test is between 65 and 130dB, use the
'Hi'range.Foranoiseenvironmentundertestthatisbetween65and
