Upper frequency limit

 
1. Upper frequency limit
DIN 4150-3 normally observes frequencies up to 80 Hz. In special cases, like for explosions, an extended frequency range up to 315 Hz may be necessary.

Lower frequency limit

 
2. Lower frequency limit
DIN 4150-3 provides for a lower frequency limit of 0,8Hz. If you want to use a divergent cut off frequency, you can enter it here. However, be aware that the measurement does not comply with DIN 4150-3 anymore.
