Additional operations		As a function of measuring simultaneously with computation, any of the following measurements can be implemented: C-weighted peak sound level LcpeakZ weighted peak sound level Lzieq * 2C weighted time averaged sound level Lceq. Since the frequency weighting of the additional computation is linked to the frequency weighting of the secondary channel, when the secondary channel is C-weighted (Z-weighted), it is possible to choose the additional computation Lceq and Lcpeak (Lzpeak)		As a function of measuring simultaneously with computation, any of the following measurements can be implemented: C-weighted peak sound level, LcpeakG weighted time average sound level, LGeqZ weighted peak sound level, Lzieq * 2C weighted time average sound level, Lceq.
