60 s
.
Read values:
In order to have permanent control of the sound pressure level before the launch of measurement, the sound level meter
calculates and displays the equivalent continuous level of acoustic pressure on a logging time of 1/8 s.
These different values are shown as:
•
A horizontal line for the maximum level
•
A full colored bar for the global level
•
An empty bar for the minimum level
➢
Move the cursor in position
