Sound Level Meter
Overload Indication
In case the measurement result exceeds the preset measure-
ment range, then limit arrows
indicate this overload condi-
tion. The arrows
are displayed for as long as the overload
exists, and at least for a minimum of 1 second. Furthermore,
such an overload condition triggers the OVR indication in the
bottom line, which remains displayed for the complete mea-
surement period. These overload indications are reset at the
start of a new measurement. All overload conditions are regis-
tered in the log and report files.
Possible causes for exceeding measurement ranges are
The measured sound pressure level exceeds the pre-set •
measurement range during the measurement period. Once
this happens, the OVR indication remains displayed for the
complete measurement period -> select the next higher
measurement range or reduce the input signal level as ap-
plicable.
The input level is near the maximum level of the connected •
NTi Audio measurement microphone.
