The noise level measurement values are made using frequency weighting A. For
carrying out frequency weightings, “slow” (1 second) and “fast” (125 milliseconds)
are available (please refer to page 25, chapter 8.3, “Measurement settings
(measurement)”).
The standard configuration of the level range is “auto”. We recommend using this
setting. Changing the level range to “Low” or “High” can be selected in the main
menu under properties/settings (please refer to chapter 8.3, “Measurement settings
(measurement)”). When the range is exceeded, it will be indicated - depending on
how long this takes - at least every second. All specifications for noise level
measurements refer to a BAPPU-evo that is
not fitted with extra accessories and
optional sensor devices.
