•
Press the DISPLAY (D) key on the numerical keyboard. The display menu will appear on
the screen.
•
To move around the display menu, use the arrow keys (A) and (B). To select an option,
press ENTER (C). To exit an option press ESCAPE (E).
•
The LRF-04 continues to work while you are inside the display menu.
•
If over two minutes pass without any key being pressed, the LRF-04 automatically exits
the display menu.
The following options are available on the display menu:
PROGRAMMING: This allows you to consult all the programmed parameters in the LRF-
-
04. These parameters are the following:
Sessions schedule: This option allows you to consult the establishment's opening
time programmed for each day of the week.
NOTE: Outside the programmed schedules, the LRF-04 attenuates 60 dB.
Regulation schedule: Use this option to consult the schedules corresponding to the
time zones of daytime and night time evaluation stipulated by the regulations
governing the establishment.
Regulation limits: This option allows you to consult data corresponding to the
maximum permitted sound pressure levels in the above time zones for the emitting
and receiving establishments.
Control mode: Use this option to display the control mode for the emitting and
receiving establishments.
ENOS: This allows you to visualize if the option ENOS is activated.
Sound insulation: This, displays the sound insulation values by standard octave
bands between the emitting and receiving establishments.
Attenuation time: This allows you to consult the duration of 60 dB penalisation.
Non-working periods: Use this option to display the non-working periods.
Leq time: With this option you can see the duration of equivalent level measurement.
Continuous printing: This allows you to see whether after each measurement interval
the date and time of the beginning and end of the interval and the continuous
equivalent level of this interval will be printed, provided a printer is connected.
Max. LF limit: This option displays the permitted maximum "Fast" level.
Modem parameters: This allows you to see the number of rings before the LRF-04
answers a request received via the modem.
- LeqT records: This option allows you to consult all the LeqT records stored in the LRF-
04. For greater convenience, first introduce the date and the time from which you want to
consult the records database. The LeqT records contain the following information:
• Date and time of the beginning of the LeqT interval.
• Date and time of the end of the LeqT interval.
• Average equivalent emission level in the interval.
• Average calculated equivalent reception level in the interval. This level is
calculated on the basis of the programmed sound insulation and the measurement
of the sound pressure level by standard octave bands with central frequencies of
31.5 Hz, 63 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz and 8 kHz.
• The maximum permitted equivalent emission level, depending on the time zone
(day or night).
• The emission control mode.
