Overload INFRA S50

You can get values tagged with overload if it’s windy for example, and then you might have to change the range settings.

If it’s windy and there are lots of wind gusts you can get values tagged with overload (there is a ”>” before the value). If overload occurs often you might have to change the range settings.

Overload can also occur for other reasons, for example if a tyre explodes not far away from the microphone.

  • Interval values are tagged with overload if analog or digital overload occurs in one single sample during the interval period.
  • Transient files are tagged with overload if analog or digital overload occurs in one single sample during recording of the transient.

Analog and digital overload

Analog overload is when the analog signal in the electronics (microphone, A/D-converter etc) is out of range, normally for a very short period. Digital overload is when an internal value in a filter algorithm needs to be saturated to avoid overflow in the calculations.

In most cases you don’t need to do anything about the overload. It’s an indication that the values peaked for some reason.
