How to Measure
Select the page • K
SET
with the rotary wheel
.
Measure the correction values k1 and k2 as described in the •
chapter Sound Level Meter: Correction Value K
SET.
Press the start button •
.
The icon • LOG flashes during the ongoing measurement. In
the case where the profile #DIN15905-5 & Audio has been
selected the icon AUD flashes, indicating the additional au-
dio wav-file logging.
During the measurement you can monitor the actual sound •
level L
Aeq5”
+k1 in order to remain below the permitted lim-
its; alternatively you may monitor the spectrum analyzer for
tracing possible feedback frequencies.
Press stop •
to finish the measurement.
In accordance with DIN15905-5, all sound lev-
els are measured, displayed and logged to the
SD Card automatically. The settings are locked,
which ensures that the correct parameters are
measured.
The profile #DIN15905-5 & Audio includes the
recording of Compressed+AGC wav-files.
