consult the measured functions prior to the temporary interruption of measurement. To
resume measurement, press
.
By pressing you stop the measurement. The state of measurement indicator will
change from to .
8.4.5 Consulting measured data
While the SC-30 is not measuring ( ), you may consult all the measured functions.
To consult them, apply the same procedure as described in the section 8.4.3 on viewing data
while measurement is in progress.
8.4.6 Overload indicator
The SC-30 is equipped with an overload indicator for each function. If overloading occurs
during measurement, the
^ sign will appear before the function affected by overloading.
When a function registers overload, its corresponding measurement is incorrect.
When overloading occurs, the indication appears at the right bottom corner of the screen.
8.5 Data registering
The SC-30 can record in the internal memory the values of the measured functions. When
switching on the equipment, the recorded data will not be lost and can be retrieved and
displayed directly from the
SC-30 or transmitted to a PC. The memory can be erased directly
from the SC-30.
Two kinds of registers may be saved in the memory:
•
The final results of a measurement.
•
Continuous recordings of functions with programmable recording time.
8.5.1 Saving final results
Once you have completed a measurement ( ), the results may be stored in the memory by
selecting the SAVE RESULTS option from the main menu. The SC-30 will indicate the
register number in which to record the data.
The SC-30 stores the following information.
•
Equivalent continuous sound pressure level with frequency weighting A corresponding to
the measurement time (L
At
).
•
Equivalent continuous sound pressure level with frequency weighting C corresponding to
the measurement time (L
Ct
)
•
Equivalent continuous sound pressure level with the integration time corresponding to the
measurement time, with frequency weighting (A) for each octave bands centred on
frequencies 63, 125, 250, 500, 1000, 2000, 4000 and 8000 Hz
•
Overall peak sound pressure level with frequency weighting C corresponding to the
measurement time (L
Cpeak
)
•
Daily noise exposure level (L
EX,8h
)
•
Sound exposure (E)
