Screens during measurements
During measurement,
three screens
inform the current measurement. They are accessible through the scrolling knob key .
S1:
it is the main screen that displays the instantaneous measurements:
•
LXY:
sound pressure level temporally weighted according to the selection
•
LAeq:
equivalent continuous level of sound pressure
A
-weighted on the measurement duration
•
LCeq:
equivalent continuous level of sound pressure
C
-weighted on the measurement duration
•
LUpk:
maximum peak level of sound pressure on the measurement duration
•
Measurement duration
in HH:MM:SS
S2:
This screen contains results of values that will be stored in memory at the end of measurement:
•
LUpk:
maximum peak level of sound pressure on the measurement duration
•
LXY Inst.:
instantaneous values of sound pressure levels temporally weighted met since the beginning of the measurement
•
LXYmax:
maximum value of sound pressure level weighted temporally met since the beginning of the measurement.
•
LXYmin:
minimum value of sound pressure level weighted temporally met since the beginning of the measurement..
To see these different results:
➢
Move the cursor with arrows keys on the item
1
and select with the scrolling knob key:
Inst. – Max – min
to read instantaneous, maximum and minimum values of sound pressure levels
LXY
S3:
this screen reminds the general format of the session of measurement:
•
Start:
date of measurement start
•
End:
date of measurement end (here, not entered
because measurement is still ongoing)
•
Duration:
measurement duration (here, on going)
•
Mode:
measurement mode (here, L- Leq)
•
Pond.:
Frequency weightings
•
Cte:
time constant
•
S/S:
Integration mode Start/Stop
•
Lpk:
frequency weighting of the peak pressure level
