Setting of the frequency weighting characteristics
There are three kinds of frequency weighting, such as A, C and FLAT. Select it by the panel switch [A/C/FLAT] according to your measurement purpose.
The frequency weighting according to the measurement purpose
Refer the following table to select the frequency weighting according to measurement application or purpose.
A-weighting |
·Applicable to general sound measurement |
---|---|
C-weighting |
·Measures approximated sound pressure level in sound measurement ·Measures criterion of magnitude of low-frequency components in comparison with A-weighted sound pressure level measurement value ·When records AC output |
FLAT |
·Measures a pressure level in acoustic measurement |
Selecting the frequency weighting
Each time you press the panel switch [A/C/FLAT] the weighting changes as follows; A-weighting, C-weighting, FLAT, A-weighting,…
