Continuous wireless availability and frequent wireless exchange of data have a
detrimental effect on the lifetime of a logger’s battery. To spare the battery, the periods
of wireless availability and activity can be restricted. To do this, the following parameters
must be entered:
Parameter Description
Radio signal
(from … to)
Beginning and end of the daily transmission window.
Select from: 0:00 to 24:00 hours
Default: 9:00 to 15:00 hours (in group mode “Patrol”) or
8:00 to 17:00 hours (in group mode “Lift&Shift”)
Explanation: The logger is ready to receive during this time and can
be configured or read. Furthermore, when a logger is in group mode
“Patrol”, it regularly transmits packets with measured data during this
time.
It is not possible to communicate with the logger outside the
given transmission window.
Transmission
interval
Transmission interval in “Patrol” mode.
Select from: 2/3/4/5/10/15 seconds
Default: 4 sec.
Explanation: Number of seconds after which a logger in group mode
“Patrol” repeats the transmission of the recorded measured data
(during the time span entered in radio signal only!).
The shorter the transmission interval, the faster a logger is detected by
the reading device as it passes by. However, long transmission
intervals spare the battery of the logger.
Transmission
days
(Mon to Sun)
Days of the week when the set transmission window applies.
Select from: Monday to Sunday
Default: Monday to Friday
Explanation: It is not possible to communicate with the logger on the
other days of the week.
The colour of the battery symbol on the bottom left of the input window indicates how
much the entered configuration will affect the service life of the logger’s battery.
Green … battery lifetime not or hardly affected
Yellow … battery lifetime badly affected
Red … battery lifetime very badly affected
If the factory-set, default configuration is used, a noise logger can be operated for about
5 years without interruption. Any extension of the measuring window or transmission
window reduces the battery’s life accordingly.
