Some display indications are common to all display modes; they are (see picture):
•
Measurement status indicator
•
Overload/Under-range indicator
•
Battery level indicator
The first symbol in the left corner at the top shows
the measurement status of the sound level meter.
•
RUN : the instrument is measuring.
•
PAUSE : the calculation of integrated measure-
ments and the recording of measurement have
been suspended. Instantaneous parameters are
still being measured and displayed.
•
REC : the instrument is measuring and re-
cording.
•
STOP : the instrument is not making any meas-
urement.
•
HOLD : the calculation of integrated measurements has come to the end of the set integration
interval, or HOLD was pressed.
•
P ( Print ): indicates that printing is in progress.
•
M (Monitor) : indicates (flashing) that continuous data printing has been started.
•
R (Replay) : appears (flashing) when the “Memory Navigator” program is in use, to view a file
saved in the instrument memory (see page 46).
Just on the right of the symbol indicating the logging mode, there is the symbol showing a
possible overload or under-range. An arrow directed upwards indicates that the input level has ex-
ceeded the maximum measurable level, while an arrow directed downwards indicates that the input
level is lower than the minimum measurable level.
The maximum measurable level corresponding to the selected measurement range is given in
the technical specifications (see page.94). The minimum measurable level is 80 dB lower than the
maximum one. The noise levels for each frequency weighting are listed in the technical specifica-
tions. Using an appropriate parameter (MENU >> Instrument >> Measurement >> Overload Level)
you can program the maximum measurable limit at lower levels (see page 94).
An empty arrow indicates that the limit has been exceeded, while a full arrow indicates that
the overload is in progress.
The integration time Tint , programmable between 1s and 99h, is displayed to the right of the
overload indicator. When the integration mode is set on MULT, the “Tint” symbol on the SLM will
flash (see the “DESCRIPTION OF THE DIFFERENT INTEGRATION MODES” on page 29).
In the right corner at the top, there is the
battery symbol . The more the symbol is empty, the
more the battery has run down. When the instrument autonomy reaches 10%, corresponding to
about 30 minutes, the battery symbol will start flashing. A protection device prevents the instrument
from making measurements with insufficient battery levels and automatically switches off the in-
strument when the battery level is at the minimum.
The battery level, expressed in percentage, is visible in the menu main screen page and in the
program page; press MENU and PROG to access them. To jump back to the measurement screen,
press MENU and PROG again.
Pressing
SELECT , you will select in sequence the parameters relevant to the displayed page.
While the selected parameter flashes, use UP and DOWN to change it. Press ENTER to quit the se-
lection mode (automatic exit after 10s).
In graphic display mode, use the UP, DOWN, LEFT and RIGHT keys to change the vertical
scale parameters. The LEFT and RIGHT keys reduce and expand the vertical scale, while the UP
