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)

the Auto-store mode.
