to allow the process of continual self-checking to be correctly carried out. If
this parameter is other than zero, the values of the SLD and SLE
parameters cannot be taken as reliable.
NOTE: It is highly unlikely that high levels of sound pressure will be
Leq time may be programmed between 2 minutes and 1 hour. The shorter the Leq time, the
more detailed the information obtained, although the memory will fill sooner. When this
occurs, the limiter continues to store records by overwriting the earliest records (FIFO
Buffer). To store one month's information, define a Leq time equal to or longer than 7
minutes. We recommend programming the LRF-05 with a Leq time of 10 minutes.
The LRF-05 also stores session records, which are kept every time a session ends (the
schedules of each session are defined in the LRF-05 programming) and contain an
exhaustive summary of what has occurred during the sessions. The sessions records contain
the following data:
 Date and time of the beginning of the session.
 Date and time of the end of the session.
 Equivalent level of the session.
 Emission exceeded during the session, in seconds.
 Reception exceeded during the session, in seconds.
 Time in seconds that the LRF-05 has penalised with 60 dB attenuation and the
average emission sound pressure level that has continued to exceed the maximum
programmed emission level during the session (Emission exceeded).
 Time in seconds that the LRF-05 has penalised with 60 dB attenuation and the
calculated reception sound pressure level that has continued to exceed the
maximum programmed emission level during the session (Emission exceeded).
 Duration of the 60 dB penalisation when this occurs (Attenuation time).
 Maximum permitted equivalent emission level for the day time zone.
 Maximum permitted equivalent reception level for the day time zone.
 Maximum permitted equivalent emission level for the night time zone.
 Maximum permitted equivalent reception level for the night time zone.
 Night time zone schedule.
 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 maximum "Fast" level measured in the session and "Fast" limit, and the
number of seconds during which the "Fast" level has exceeded the limit
programmed for the session (emission).
 The percentiles obtained in the session: L1, L5, L10, L50 and L90 (emission). An
Lx percentile indicates the sound pressure level exceeded during x% of the
interval.
 Summary of the Mains disconnections that have taken place during the session.
 Time in seconds during which the sensor was tampered with during the session
(Sensor inactive).
The following information is also accessible:
- REPROGRAMMINGS: the ten last dates on which the LRF-05 was programmed
(date+hour:minute:second).
