calibrating process or the process is aborted, the continuous internal self-checking system
will be deactivated. To reactivate it, simply calibrate the LRF-05 again.

4.4 Real time display

To see the data measured by the LRF-05
the option from the programming menu. The following information is displayed:

Date and time of the LRF-05

The attenuation applied by the LRF-05 in numerical and graph format (progress bar)

Indicator of the state of the LRF-05: session, day/night

Indicator of the sound pressure level measured in the establishment (L
measured level is below 60 dBA, UND will appear. If the level is above 120 dBA, UP
will appear

If the sensor has been tampered with, the message SENSOR INACTIVE will appear
on the progress bar as long as the manipulation lasts. The sound pressure level
indication will be replaced by three dashes (- - -), since it will not have been possible
to measure this level

When the date and time correspond to a non-working period, the NON-WORKING
PERIOD message will appear
The type of communication (USB or modem) and the communications port must be correctly
defined.

4.5 Verification of the measured parameters (test)

This LRF-05 option allows you to see, in real time, the following sound parameters measured
by the sensor:

Continuous equivalent level (dBA) and duration of the measurement (s)

Continuous equivalent 1s level (dBA)

Fast level(dBA)

Maximum Fast level (dBA)

Continuous equivalent level (dB) of the 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.

4.6 Deleting records

This option allows you to delete all records stored in the LRF-05 memory except for the
programming, the counter of the times record deletion has taken place and the record of the
last ten deletions.
To access this option in the programming menu, press

4.7 Changing the password

The programming, real time, calibration, test, deletion and change password options are all
rotected by a password. All LRF05s have the same ex-factory password: 0000. We strongly
recommend that you change the password. To change the password, press the button
in the programming menu. Then introduce the current password, the new password, and
confirmation of the latter.

4.8 Downloading data

The LRF-05 application software allows you to download the data recorded by the limiter into
a PC in the following way:
in real time, all you have to do is select
