Warning and Precautions
• for wind speeds over 10 m/sec (22.3 mph), use the windscreen on the
microphone.
• for general sound level measurements use A weighting. for checking the
low-frequency content of noise use C weighting. if the C-weighted level
is much higher than the A-weighted level, then there is a large amount of
low-frequency noise
• for normal measurements use the fAST mode. for checking average level
of fluctuation noise use the SLow mode.
