• The maximum "Fast" level measured in the interval and the number of seconds
during which the "Fast" level has exceeded the limit programmed for the interval
(emission).
• Level, date and time of the maximum 1-minute Leq obtained during the interval
(emission).
• Level, date and time of the minimum 1-minute Leq obtained during the interval
(emission).
• Time in seconds during which the LRF-04 has been disconnected from the mains
during the interval (Disconnections).
• Time in seconds during which the sensor has been tampered with during the
interval (Sensor inac.).
• Records corresponding to the continuous self-checking system (when activated,
see 2.4):
• SLD (Sound Level Deficiency): this parameter shows us the number of
• SLE (Sound Level Excess): This parameter indicates the number of
• IL (Insufficient Line signal): this parameter records the number of minutes
• The percentiles obtained in the interval: L1, L5, L10, L50 and L90 (emission). An
Lx percentile indicates the sound pressure level that was exceeded during x% of
the interval.

minutes during which the sound level measured by the sensor was lower
than expected. This may be due to the sensor has been tampered with.
minutes during which the sound level measured by the sensor was higher
than expected. Such excess in the sound pressure level are usually due to
sound sources outside the hi-fi equipment in which the LRF-04 is installed.
The most common situations are those in which the customers themselves
make a lot of noise or sound levels are produced by supplementary
equipment.
during which the music line signal introduced into the limiter was insufficient
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
obtained when the IL parameter indicates that the line level is
insufficient.
