The equivalent continuous sound pressure level with time
averaging ‘I’ belonging to the measurement period, measured
with frequency weighting A, C and Z
L
XIT

XT
The subtraction of the equivalent continuous sound pressure
level with time averaging ‘I’ and the equivalent continuous sound
pressure level, corresponding to the programmable integration
time T. These two functions measured with frequency weighting

X: Any of the frequency weightings A, C or Z
When you access the advanced sound-meter mode, the following screen will appear:
When you press the frequency weighting will change (for the functions indicated).
By pressing you access the numerical sound-meter screen.
NOTE: The functions values will be refreshed on the screen each second.
