3. DATA REGISTRATION
The values of the measured functions may be stored in the SC-30 internal memory. When
the unit is switched off, the data is saved and may be retrieved and displayed directly from
the SC-30 or transferred to a PC. The memory may be erased directly from the SC-30.
Two kinds of registers may be stored in the memory:
•
The final results of a measurement
•
Continuous recordings of functions with programmable register time.
3.1 Saving results
Once a measurement has been completed ( ), the results may be stored in the memory. Do
this by selecting the SAVE RESULTS option from the main menu The SC-30 indicates the
memory number under which the data has been saved.
The SC-30 saves the following information:
•
Sound level meter mode:
o
Sound pressure level with ‘F’ time weighting (Fast)
o
Sound pressure level with ‘S’ time weighting (Slow)
o
Sound pressure level with ‘I’ time weighting (Impulse)
o
Equivalent continuous sound pressure level with T integration time
And their maximum and minimum values.
o
The equivalent continuous sound pressure level for the entire measurement
o
The sound exposure level SEL.
o
The peak sound pressure level
All measured with frequency weightings A, C and Z.
o
Measurement and integration times
o
Total percentiles 1%, 5%, 10%, 50%, 90%, 95%, 99%
•
Spectrum analyser mode:
o
The equivalent continuous sound pressure level with T integration time for the
octave bands centred on the frequencies 31.5, 63, 125, 250, 500, 1,000,
2,000, 4,000, 8,000 and 16,000 Hz (without frequency weighting).
o
Peak sound pressure level of the T interval for the octave bands centred on
the frequencies 31.5, 63, 125, 250, 500, 1,000, 2,000, 4,000, 8,000 and
16,000 Hz (without frequency weighting).
o
Equivalent continuous global sound pressure level with T integration time and
frequency weightings A, C and Z.
o
Maximum peak sound pressure level of the T interval and with frequency
weightings A, C and Z
o
The integration time T.
The SC-30 may store a total of 1,000 final results in both sound level meter mode and
spectrum analyser mode.
