tinue display updating, just press the HOLD key. When the continuous recording is activated and
the Tint time goes over, the acquisition is stopped automatically.
If you press HOLD during the measuring phase, the display update will be temporarily inter-
rupted. When HOLD is pressed again, the updating will continue. Even if the display is not updated,
the instrument will go on measuring.
If you press PAUSE, the acquisition will be temporarily suspended. While in pause, press
START/STOP/RESET to clear the graph. Press PAUSE once more to start measuring again.
If you press CURSOR at any moment, a cursor will be activated. If you press CURSOR
once more, a second cursor will activate, while, if you press it for the third time, both cursors will
be activated in “tracking”. Use the LEFT and RIGHT arrows of the keypad to shift the selected cur-
sors into the desired position to indicate the measured level and the corresponding acquisition time.
Press CURSOR again to disable cursors.
Press PRINT at any time to print the on-screen data. To activate the continuous printing
(Monitor), press and hold down PRINT for at least 2 seconds. The flashing letter M, over the status
indicator, indicates that the Monitor function has been activated. The Monitor function remains ac-
tive even when jumping to other measuring views and can be disabled pressing PRINT again or
START/STOP/RESET to stop measurement.
Spectrum
(by octave and optional third octave bands) - See also the description on page 20.
Press MODE to view the SPECTRUM screen by octave or third octave bands (with the
“Third Octave” option), where the frequency spectrum by constant percentage bandwidths is dis-
played. Use SELECT to set the integration time or the frequency weighting of the wideband auxil-
iary channel, as described in the paragraph “Spectrum Mode” on page. 20. Alternatively, measuring
parameters can be set from menu, as described in “DESCRIPTION OF THE MENU FUNCTIONS”
a pag. 39. Once parameters have been set via the START/STOP/RESET key, the execution is
started.
If the sound level meter is set with the single integration mode (MENU >> Instrument >>
Measurement >> Integration Mode: SING), once the Tint time (in common with the SLM screen) is
over, HOLD will appear and the spectrum updating will be temporarily suspended. Meanwhile, the
instrument goes on measuring: to continue display updating, just press the HOLD key. If you press
HOLD during the measuring phase, the display update will be temporarily interrupted. When
HOLD is pressed again, the updating will continue. Even if the display is not updated, the instru-
ment will go on measuring.
Also data acquisition can be temporarily suspended with the key PAUSE. To clear the graph, when
in pause, press START/STOP/RESET. Press PAUSE once more to start measuring again.
Press PRINT at any time to print the on-screen data. To activate the continuous printing
(Monitor), press and hold down PRINT for at least 2 seconds. A flashing M over the status indica-
tor, shows that the Monitor function is active. The Monitor function remains active even when
jumping to other measuring views and can be disabled pressing PRINT again or
START/STOP/RESET to stop measurement.
When integration mode is multiple (MENU >> Instrument >> Measurement >> Integration
Mode: MULT), the integrated levels are cleared just before the beginning of each measurement cy-
cle. The MONITOR function allows sending to the serial interface the integrated spectrum at inter-
vals equal to the Tint time. Recording in Auto-Store mode allows to store on memory octave and
third octave (if this option is installed) spectra together with the parameters displayed on the SLM
screen at a rate corresponding to the Tint time.
Press REC for 2 seconds at any time to store the displayed data. As soon as data are saved on
memory, a screen will allow you to enter the recording title. Activating the single data recording,
while in STOP mode, is first asked to choose between automatic (Auto-Store) or manual recording).
