Weight 105 g ( 26% lighter than previous model)
Standard compliance Measurement Act, JIS C1509-1 Class 2, IEC 61672-1 Class 2
Measurement functionality Sound level, equivalent sound level, sound exposure level, maximum sound level, and C-weighted peak sound level

A-weighting: The human ear hears different frequencies at different volumes. A-weighting, which employs a filter tuned for the frequency characteristics of the human ear, is used in most sound measurement applications.
C-weighting: C-weighting uses a flat frequency filter.
F ( fast) : Fast measurement is designed to mimic the response of the human ear. F-weighting is used in most sound measurement applications.
S ( slow) : Slow measurement employs a slower response in order to make it easier to read indicated values.
