18.1.5 Store data
Same as the 1/1 octave mode operating: please see the chapter
Store data
page 29.
18.1.6 Read the file data in 1/3 octave mode
When the file is found by its identification number:
➢
Press
OK
to access the
S1
general screen which displays the measurement configuration:
•
Date of measurement start
•
Date of measurement end
•
Measurement duration in
DD/HH:MM:SS
•
1/3 oct measurement mode
: Mode
•
Filters by octave bands from 12.5 Hz to 20 kHz (class 1) or from 25 Hz to 10kHz (class 2):
F
•
Elementary integration time for LXeq:
DI
•
Frequency weighting of the peak pressure level:
Lpk
•
Audio record activated or not:
Audio
S2:
main screen which displays the values and a spectral type graphical representation.
The different bars represent:
•
LAeq
-
LCeq - LZeq:
equivalent continuous levels of A, C, Z weighted acoustic pressure
•
LXeq:
equivalent continuous levels of acoustic pressure filtered by third octave bands from 12.5 Hz to 20 kHz
•
The
Measurement duration
expressed in DD/HH:MM:SS completes the display
Read the values:
➢
Put the cursor in position
1
with the arrows and choose among
DI- global – Max - min
➢
Move the cursor in position
2
with the vertical arrows then choose with the scrolling knob key the
weighting or filter value and read the result display in box
3
.
A vertical line is moving on the screen and is overlapped with the bar corresponding to the weighting or
filter chosen in
2.
➢
Proceed the same way to read the different values according to the choice in
1: DI – global – Max - min
•
DI:
weighted and filtered continuous equivalent levels for each DI elementary integration time (01 s
for example)
•
Global:
weighted and filtered continuous equivalent levels of the current measurement
•
Max:
maximum weighted and filtered continuous equivalent levels reached since the measurement start
(basis: DI elementary integration duration)
•
min:
minimum weighted and filtered continuous equivalent exceeded since the measurement start (basis: DI elementary
integration duration)
These different values a represented:
•
by a horizontal line for the level
max
•
a full colored bar for the
global
level
•
an empty bar for the
min
level
