About The Mobile App - B&K 2245 User Manual

The instrument performs frequency analysis of either 1/1- or 1/3-octave spectra (Leq, Lmax, Lmin) with one of the avail-
able frequency weightings (A, B, C, Z) and time weightings (F, S).
The instrument takes single measurements. In other words, the instrument calculates a single value for each measured
parameter for the total measurement time.
The instrument takes logged measurements. In other words, it has a logging mode that can average and log intervals of
broadband and/or spectral data to obtain a profile of the total measurement with logging intervals between 1 s and 1
min.

levels.
