Press the Leq/Lx button to successively display the Lmax, Lmin, Time (elapsed), SPL, SEL and Record
number of the current measurement.
Leq: The equivalent continuous sound level is the average level since the beginning of the average period.
Lmax: The maximum sound pressure level is the highest value recorded during the current averaging
process.
Lmin: The minimum sound pressure level is the lowest value recorded during the current averaging
process.
SPL: Sound Pressure Level: current noise level according to the time response settings. (FAST or SLOW)
SEL: The sound exposure value is the equivalent total sound energy of a measurement over 1 second. It is
mostly used for fluctuating measurements over a short period of time, like a car passing by.
REC: Record number of the last stored data in the Piccolo’s memory in Manual mode, or current data in
the Auto-store mode.
Time: Elapsed time of the current averaging process.
