The 24X Series has a simple user interface using two ‘softkeys’,
which represent options displayed at the bottom of the screen.
This makes the instrument very easy to use and any setup changes
are retained the next time the unit is switched on. To accurately
measure fluctuating noise levels, the CEL-246 model measure
average values, integrated over time; Leq for European Standards
and Lavg for the USA. In order to quantify how noise varies with
time, the CEL-246 logging variant (CEL-246 stores 419,000 data
points) is also available to store the time history of the noise levels
as well as the levels for the overall measurement (e.g. maximum
and average levels, as detailed in the table below).
dB24 Software
This optional software allows
the CEL-246 real-time USB
output to be logged and
stored on a PC. Sound
pressure levels are stored
by dB24 every second into
a data file compatible with
PC based spreadsheet
applications. Data stored
within the CEL-246 can also
be accessed since these meters act like a memory stick, allowing
transfer of data to spreadsheet applications.
