The different bars stand for:
•
LAeq
-
LCeq - LZeq:
equivalent continuous levels of sound pressure A, C and Z-weighted
•
LXeq:
equivalent continuous levels of sound pressure filtered by octave bands from 16 Hz to 16kHz (class 1) or from 31.5 Hz
to 8 kHz (class 2).
•
Measurement duration in DD/HH:MM:SS
Read values:
➢
Move the cursor in
1
with the arrows and select among
DI - global – Max - min
➢
Move the cursor in
2
with the arrows and select with scrolling knob key the value of weighting or
filter and read the result displayed in the box
3
.
A vertical line is moving on the screen and superimposes on the bar corresponding to the selected weighting
or filter.
Do the same to read the different values according to the selection in
1: DI – global – Max - min
•
DI:
equivalent continuous levels weighted and filtered for each DI logging time (01 s for example)
•
Global:
equivalent continuous levels weighted and filtered of the ongoing measurement
•
Max:
maximum equivalent continuous levels weighted and filtered reached since the
beginning of the measurement (base: DI logging time)
•
Min:
minimum equivalent continuous levels weighted and filtered reached since the
beginning of the measurement (base: DI logging time)
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
S2:
this screen displays the results of current values that will be stored at the end of the measurement.
➢
Move the cursor in
1
with the arrows and select with the scrolling knob key among
DI - global – Max - min
Read the different values according to the selection.
•
DI:
equivalent continuous levels weighted and filtered for each DI logging time (01 s for example)
•
Global:
equivalent continuous levels weighted and filtered of the ongoing measurement

•
Min:
minimum equivalent continuous levels weighted and filtered reached since the beginning of the
measurement (base: DI logging time)

Date of measurement end: not entered because measurement is still ongoing.
•
Measurement time: not entered because measurement is still ongoing.
