Measurement
When using the unit in a mode other than “sound level measurement”, all
processing functions provided by the unit (
L
eq
,
L
E
,
L
max
,
L
min
,
L
N
) are carried out
simultaneously. (However, for the sub channel, only the additional processing
function set to “ON” in the menu list screen is carried out.) For example,
when equivalent continuous sound level measurement is selected, the sound
exposure level and percentile sound level are also determined. However,
the time percentage setting for the percentile sound level (5 values) must be
selected beforehand.
To display measurement values other than sound level, you need to set desired
items to ON on the [Display] screen from the menu list screen.
Also, make sure that the date and time are set correctly, as described on
page 26.
Sound level (
L
p
) measurement
The procedure for sound level measurement is described below.
Preparations as described in the “Preparations” chapter must be completed fi rst.
1. Press the POWER key to turn the unit on.
After the power-on screen has been shown, the measurement screen
appears.
The measurement parameter settings that were active before the unit
was turned off will be established again. Therefore the actual display
may not always be the same.
