4) Access the SETTINGS SENSITIVITY ADJUST option.
5) The display will show the sound pressure level measured by the SC-30 and the time
and date of the last time the sensitivity was modified:
6) Use the keys and to adjust the calculated value (94 dB + corrections).
7) Confirm by pressing the key (the sensitivity will be modified and the date and
time will be updated)

2.3 Measuring in sound level meter mode
The sound level meter mode is suitable for measuring global sound pressure levels, both
instantaneous and averaged based on integration (equivalent level). The SC-30
simultaneously measures all the functions with all the frequency weightings (A, C and Z) and
provides statistical data of the measurements, including maximum and minimum values and
percentiles (see
APPENDIX A
).
Outstanding among the applications of the SC-30 are its ability to measure the sound level of
noisy activities, urban and road traffic, and machines such as pneumatic drills and pumps, to
measure appropriate parameters to ensure sound protection for workers and to measure
sound parameters to evaluate levels of sound pollution, etc.
2.3.1 Prior adjustments: Preferential screen and integration time
Before beginning measurement in sound level meter mode, the following parameters should
be configured:
•
The 3 functions that appear simultaneously on the numeric preferential screen.
•
The integration time for the equivalent continuous sound pressure level function with T
integration time. This integration is carried out in consecutive T-second intervals.
To configure these parameters, access the SETTINGS MEASURING SOUND LEVEL
METER option on the SC-30 menu ( 2.6.2).
