L50, L90, L95, L99, maximum values, duration
of measurement and Leqt with programmable
t.
• 23 – 140 dB measurement range
• One single range (no range changes)
Features
• Type 1 integrating sound level meter
meeting EN 60651 and EN 60804
• A and C frequency weightings
• Allows you to store the measurement
results in the memory and save all the
measured parameters second by second
for 3 hours
• Equipped with AUTOSTORE recording
for long-duration (1 week) Leq measurements
• Includes software to transfer all measured
and recorded parameters to a PC
• Detachable preamplifier for use of the
extension cable (CN-010) and the semipermanent
outdoor kit (TK-1000)
The SC-20e is a user-friendly, high performance Type 1 integrating-
averaging sound level meter. It measures all functions
simultaneously and displays the one selected on the screen
when the function selector is activated. Once one measurement
is completed, they can all be consulted along with their
maximum values and percentiles. The SC-20e needs no range
changes as its single range encompasses the entire measurement
range.
The SC-20e can be connected to a computer. The SC-20e is
supplied with a programme for PC or compatible unit that permits
communication with the SC-20e, graphical and numerical
presentations, storing results on the hard disk, statistical analyses
and so on. The unit can also be connected to a printer to
print out the values of the function selected. At the end of each
printout a summary appears with the value of all the functions
and a statistical analysis.
The DC output of the SC-20e maintains a constant tension
equivalent to the value displayed on screen. This output allows
you to connect the unit to a graphic recorder. The AC output
gives you the preamplifier output signal without frequency
weighting. This output can be used for the
calibrated recording of the measured signal on DAT
or magnetic tape.
The CESVA SC-20e integrating-averaging sound
level meter allows you to make RECORDINGS of
the measured data, store MEMORIES of the final
results of the measurements and make AUTOSTORE
recordings of the equivalent continuous level.
A RECORDING stores all the measured data second
by second. The MEMORY saves only the
final result of a measurement. The AUTOSTORE
recordings allow you, for a programmable
period, to store 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 only
be retrieved by using the PC software designed
for the SC-20e sound level meter.
The SC-20e preamplifier is removable, allowing
it to be detached and placed at a distance
from the SC-20e using the extension cable.
There is also an outdoor kit (TK-1000) for taking
measurements in the open air.
