Licences
B&K 2245 is a type-approved sound level meter (SLM). However, this basic functionality can be extended with optional
licences; it can perform frequency analysis, log broadband and spectral data, perform statistical analysis and make audio
recordings.
Licences for the instrument control the functionality of the instrument and to which applications it can connect.

About
About the Instrument
The instrument measures basic sound level meter parameters (Leq, Lmax, Lmin and Lpeak) with up to two sim-
ultaneous frequency weightings (A, B, C, Z) and up to three simultaneous time weightings (F, S, I) for the exponential
averaging.
✐ Note: Licence BZ-7304 (Exhaust Noise Partner) enables basic parameters (Lmax and Lmin) with one frequency
