2.6 Overload Indication
The overload LED will blink for 1s when an overload occurs. If the overload occurs
during a measurement, the right-most segment of the SPL Bar Graph will blink. This
segment will keep blinking until another measurement is performed.
The overload threshold is set 1 dB below the upper limit of the dynamic range.
