An Integrating Sound Level Meter with
Type 1 Impulse precision. Its comprehen-
sive construction and versatility make it
ideal for all kinds of sound level measure-
ments including octave and
113
octave fre-
quency analysis using a snap-on filter set.
The Type 2230 carries out five measure-
ments in parallel: SPL, Max., Min., Leq and
SEL, all of which can be obtained for the
same signal. A choice between 2 detector
modes (RMS and Peak), 3 time weightings
(Slow, Fast, Impulse), 4 frequency weigh-
tings (A, C, Lin and All-pass) is available
for the measurements.
A partial (Max./Min.) reset, a total reset
and a pause function increase the use-
fulness of the instrument. A linear free or a
linear diffuse field frequency response is
obtained by electronic frequency weighting.
The SPL is continuously monitored on a
quasi-analogue 60 dB scale. Warnings of
overload, depleted batteries and illegal set-
tings are also given. AC and DC outputs
allow chart or tape recording and audio
monitoring of the SPL.
