A/C FREQUENCY WEIGHTING

weighting selected, the frequency response of the meter is similar to

environmental or hearing conservation programs such as OSHA

weighting is a much flatter response and is suitable for the sound
level analysis of machines, engines, etc. Most noise measurements
are performed using 'A' Weighting and SLOW Response.

FAST/SLOW RESPONSE TIME

Use the FAST/SLOW button to select a FAST (125 ms) or a SLOW (1
second) response time. Select FAST to capture noise peaks and noises
that occur very quickly. Select the SLOW response to monitor a sound
source that has a consistent noise level or to average quickly changing
levels. Select SLOW response for most applications.
