is measured,
select the frequency weighting here.
Note: X = frequency weighting A or B. ‘A’ requires
that the Broadband (excl. Peak) parameter is set to
AC or AZ. ‘B’ requires that the Broadband (excl.
Peak) parameter is set to BC or BZ
The settings G, Wm and Wmb are available for Low
Frequency = Extended or Very Low
Requires Low Frequency Option BZ-7234
