3. DATA REGISTERING
The SC310 built-in memory registers the values of the measured functions. When you switch
off the unit the saved data is not lost and may be retrieved and displayed directly on the
SC310 or downloaded into a PC. The memory may also be erased directly from the SC310.
Two kinds of registers may be saved in the memory:
•
The final results of a measurement.
•
Continuous recordings of functions with programmable recording time.
3.1 Saving 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 SC310 will indicate the
register number in which to record the data.
The SC310 stores the following information:
•
Sound level meter mode:
o
Sound pressure level with fast frequency weighting.
o
Sound pressure level with slow frequency weighting.
o
Sound pressure level with impulse frequency weighting.
o
Continuous equivalent sound pressure level with integration time T.
And their maximum and minimum values.
o
Continuous equivalent sound pressure level of the entire measurement.
o
The sound exposure level (S.E.L.).
o
The sound pressure peak level.
o
Continuous equivalent sound pressure level with impulse frequency weighting
and integration time T for the entire measurement.
All measured with frequency weightings A, C and Z.
o
Date and time of the beginning of measurement
o
Measurement and integration times.
o
Total percentiles: 1%, 5%, 10%, 50%, 90%, 95% and 99%
•
Spectrum analyser 1/1 mode:
o
Continuous equivalent sound pressure level with integration time T for octave
bands centred on frequencies 31.5, 63, 125, 250, 500, 1000, 2000, 4000,
8000 and16000 Hz (without frequency weighting).
o

250, 500, 1000, 2000, 4000, 8000 and16000 Hz (without frequency weighting)
and for the overall value with frequency weighting A.
o
Continuous overall equivalent sound pressure level with integration time T and
frequency weightings A, C and Z.
