The measure will stop by itself after time T previously chosen for the measurement of the S1 source.
The equivalent continuous level calculated from the two combined sources is displayed in front of '
S1 + S2
'.
5.5.3 Store data
At the end of the measurement a screen of all results is displayed. It is then possible to :
➢
Accept measurements and store them : move the cursor on
Sto.
and press once on OK key to confirm. A banner displays the
storage phase.
➢
Reject measurements and not store them : move the cursor on
RST
and press
twice
on OK key to confirm. A banner displays
the phase of data deletion.
5.6 Determine a sound source among two
Example :
outdoor heat pump in a background noise of day
.
Estimate the sound level of a heat pump without the background noise of day, to estimate the possible nuisance of the heat pump in a
noise environment less noisy as the one present the night.

Deletion
The determination of a sound source among a set of two can not run unless the operator can interrupt one of the
two sources, the aim being to estimate the sound level of a source without the presence of the other source.
