To set this parameter, select the SETTING
Î
SPECTRUM ANALYSER option from the
SC310 menu.
Press
to begin setting the T parameter and then follow the procedure detailed below:
•
Choose the numerical value using
and
and confirm by pressing
. T
integration time may be set from:
o
1 to 59 seconds (1’’ – 59 ’’)
o
1 to 59 minutes (1’ – 59’)
o
1 to 99 hours (1H – 99 H)
•
Finally, select the time units: seconds ( ’’ ), minutes ( ’ ) or hours ( H ) with the help of
and
and press
to confirm. Use
to cancel or return to the
menu.
•
If you select "t" as the integration time numerical value (it lies between values 1 and 99),
the integration time will coincide with the measurement time. This is a practical option
when it comes to evaluating the ideal integration time. To apply this option, carry out a
measurement with "t" integration time and calculate the time needed for the bands in which
you are interested to stabilise.
2.4.2 Beginning measurement
First of all, ensure that the sound level meter is not carrying out any measurement process
( ). If it is ( or ) press
to stop it.
Next, set the SC310 in spectrum analyser 1/1 mode and select the screen you want to view
(numerical, graphic statistical or NC spectrum analyser 1/1) using the keys:
One you have selected the screen, press
to set the measurement process in motion.
2.4.3 Functions display
The
SC310
measures all functions simultaneously. Described below are the different ways of
displaying the acoustic functions while measurement is taking place. If you change the kind
of display (screen), octave band or parameter, measurement will continue uninterrupted.
While measurement is in progress, however, you cannot switch from one measurement
mode to another.
