LRF-04
User’’s manual
33
-
Maximum permitted equivalent emission level for the night time zone.
-
Maximum permitted equivalent reception level for the night time zone.
-
Equivalent session level.
-
Duration of 60 dB penalisation, when this occurs (
Attenuation time
).
-
Emission exceeded
: time in seconds, during the interval, that the sound
pressure measured in emission has exceeded the maximum emission
level programmed, or, the LRF-04 has applied an attenuation of 60 dB, or
with the ENOS option activated, the LRF-04 has overridden the
attenuation.
-
Reception exceeded
: the definition as for emission exceeded, but for the
maximum reception level programmed.
-
Time in seconds during which the LRF-04 has penalised with 60 dB
attenuation and the measured emission sound pressure level has
continued to exceed the programmed limit during the session (
Emission
exceeded
).
-
Time in seconds during which the LRF-04 has penalised with 60 dB
attenuation and the calculated reception sound pressure level has
continued to exceed the programmed limit during the session (
Reception
exceeded
).
-
Time in seconds during which the LRF-04 has been disconnected from the
mains (
Disconnections
).
-
Time in seconds during which the sensor has been tampered with during
the session (
Sensor inac.
).
-
Maximum “Fast” level measured during the session and the number of
seconds during
which the “Fast” level has exceeded the programmed limit
for the session (emission).
-
Level, date and time of the maximum 1-minute Leq obtained during the
session (emission).
-
Level, date and time of the minimum 1-minute Leq obtained during the
session (emission).
-
The percentiles obtained during the session: L1, L5, L10, L50 and L90
(emission). An Lx percentile indicates the sound pressure level exceeded
during x% of the interval time.
-
BATTERY RUN OUT: Before the battery runs out, the LRF-04 records the day and time
when this occurred. You may consult the last 10 times this happened by selecting this
option from the display menu.
-
REPROGRAMMING: This option allows you to consult the last 10 dates on which the
LRF-04 was programmed.
-
DELETIONS: This option tells you the last 10 occasions on which the LRF-04 data was
deleted.
