1.2 Main features of the SC-30
The SC-30 is an easy-to-use sound level meter that allows you to make sound
measurements quickly and conveniently.
The most important features of the SC-30 are the following:
•
The SC-30 has a single user range; there is therefore no need to adjust the scale prior to
beginning a measurement, whatever the sound event to be measured.
•
Whether you use it as a sound level meter or spectrum analyser, the SC-30
simultaneously measures all functions with all the available frequency weightings (A, C
and Z).
•
The SC-30 preamplifier is detachable. You can uncouple it and move it away from the SC-
30 by using the extension cable (CN-010). The instrument can be complemented with an
outdoor kit (TK-1000) for taking measurements in the open air.
•
The SC-30 is equipped with communications software, allowing you to configure the
instrument and download all the recorded data and real-time measurements into a
personal computer. This way they can be viewed in electronic format.
•
The SC-30 AC output is designed to pick up the direct preamplifier signal. This allows you
to make a calibrated recording on a D.A.T. and subsequently analyse it both quantitatively
(impulse or tonal sound level analysis) and qualitatively (exceptional sound event –
shouts, undesirable noises, etc. – detection). The SC-30 is equipped with a 40 dB built-in
amplifier to adapt the measurement range to the recording dynamic range.
•
The SC-30’s graphic screen displays the measured functions in both graphic and
alphanumeric formats. The graphic display is highly practical when it comes to studying a
sound event, evaluating its time history or analysing its spectral contents. The SC-30’s
screen lights up at the push of a button, allowing you to work in dim conditions or in the
dark.
•
The SC-30’s membrane keyboard is absolutely flat. This way its excellent sound response
is never impaired.
•
The SC-30 has an internal memory for storing measured data. The storage of these data
in the memory is configurable, allowing you to adapt the form of data recording to the kind
of measurement being conducted.
•
The SC-30 stores in memory the time and date of the last time the sensitivity was
modified. (See
2.2.3)
•
The SC-30 has multiple language support and once a language is selected, it will remain
selected even if the unit is turned OFF (see paragraph
2.6.5)
•
Both pre-polarised and 200 volt polarised microphones are supported by the SC-30. They
need the appropriate preamplifier to correctly work.
