7. MEMORIES AND RECORDINGS
The
SC-20e sound level meter allows you to make RECORDINGS of the
measured data, store MEMORIES of the final measurement results and make equivalent
continuous level AUTOSTORE recordings. While measurement is in progress, a
RECORDING stores all the data being measured. These parameters are stored every
second as measurement lasts. On the other hand, a MEMORY stores the final result of a
measurement once it has been made. AUTOSTORE recordings allow you to store in a
memory, and during a programmable period, consecutive equivalent continuous level
measurements corresponding to an integration time which is also programmable. All the data
stored in the sound level meter's internal memory (recordings, memories and autostore
recordings) may be retrieved only by the PC software specially designed for the SC-20e
sound level meter.
7.1 Memories
The SC-20e allows you to store in a memory the final result of a measurement once it has
been completed (the screen will flicker). Each stored memory is assigned an internal identity
number. Each memory contains the following data: the value of all the functions and their
maximums; the frequency weighting used (A or C); and the date and time of the beginning
and end of the measurement. The flat battery and overload indicators are also stored
together with the measurement statistics.
In order for a measurement to be stored in memory, it must be completed (the screen will
flicker). Press the "Run/Stop" key [9] until the "Sto" message appears on the screen. As
shown in the figure below, first "Run" will appear, followed by "Sto". At this moment release
the key, and the number associated with the memory will appear on screen. This number
increases each time a measurement is stored in the memory. Next the sound level meter
screen will flicker again, meaning that the instrument is ready for another measurement.
7.2 Recordings
The recording process allows you to carry out a measurement, and store the data measured
by the sound level meter in the memory every second. Data stored are: the value of all the
functions and their maximums; frequency weighting (A or C); date and time of the beginning
and end of each measurement; and flat battery and overload indicators. At the end of the
measurement process, the measurement statistics are added to the stored information.
When the screen starts flickering, a measurement with recording may begin. Press the
"Run/Stop" key [ 9 ] until "rcd" appears on the screen, as shown in the following figure:
Once "rcd" appears on the screen, release the "Run/Stop" key [9]. The number associated
with the recording will appear on screen. The figure on the recordings counter, which is
different from the memories counter, automatically increases each time a recording is made.
Next the sound level meter will begin measuring, and will store the information described
