Ouput

DB 100 sound level meter is reliable, easy to use and in accordance with metrology requirements. DB100 can measure :

- Sound-pressure level

- Time averaged or equivalent continuous sound pressure level

DO NOT PLUG USB cable. The output is not USB compatible, the plug is maintenance- and optional accessory-specific.

Sound-pressure level LA

as per two weighting times FAST or SLOW

Time averaged sound level LAeq

To be used for stable or slightly fluctuating sound sources.Sound-pressure level (L

A ) unit is dBA and L

Amax and

LAminvalues are saved.

To be used for fluctuating sound sources.Time averaged sound level (L

Aeq) unit is dBA with a

programmable integration time in minutes and seconds.
