V4.1
SLM (
SOUND LEVEL METER MODE
)
This is the display mode upon power on.
Three parameters (selectable among the following ones) can be displayed simultaneously:
•
Instantaneous acoustic descriptors such as L
p
, L
eq
(Short) and L
pk
. The instantaneous pres-
sure level is displayed as the maximum level reached every 0.5s.
•
Integrated acoustic parameters with wideband frequency weightings, such as L
pmax
, L
eq,
L
Ieq
and L
pkmax
, updated every 0.5s.
•
Percentile levels selectable between L
1
ad L
99
.
•
Sound exposure level.
•
Daily personal exposure level.
•
Dose and daily Dose with programmable Exchange Rate, Criterion and Threshold Levels.
•
Overload Time (in %).
The display is updated every 0.5 seconds.
The data recording depends on the integration mode selected (single or multi) and on the activation
or not of the
Auto-Store function change the recording functioning as described in the table below
(see the chapter “DESCRIPTION OF THE DIFFERENT INTEGRATION MODES” on page 29).

Automatic reset of integrated levels at
every integration interval.
Automatic recording of SLM page, to-

THIRD OCTAVE, at intervals equal to the
set integration time. At the beginning of
each period, integrated levels and spectra
are set to zero.

ESCRIPTION
Left at the top of the display there are the recording status symbol and the overload or under-
range indicator (described at the beginning of this chapter). In the midst there is the integration in-
terval and on the right the acquisition time (hours:minutes:seconds). When the integration mode is
set on MULT (Menu >> Instrument >> Measurements >> Integr.: MULT), the “Tint” symbol
flashes. The battery symbol is in the right corner, indicating battery level.
