Note: As a part of the SV 271 LITE station SVAN 971 is powered from the
external source and doesn’t use its internal batteries. Internal instrument’s
batteries must be removed for correct system operation and safety reasons!
To extract the batteries
the user should switch
off
the
instrument,
unscrew the bolt, take
off the black bottom
cover of the instrument
and slide the batteries
out.
The user should then fix the bottom cover back on.
SVAN 971 is delivered with 8GB micro SD-card.
The user may exchange it for a 32GB card, but before insertion the card must be
formatted as FAT32.
The micro-SD Memory Card is in the slot under
the bottom cover and can be accessed after the
bottom cover is removed.
To extract the card from the card-slot, the user
should push on the card and then pull it out of the
slot.
There are some important settings, which should be assured in the instrument as a
part of the monitoring station:
1. The
Compensation Filter
should be set to
Outdoor: Environment
or
Outdoor: Airport
filter (
path: <Menu> / Measurement /
Comp. Filter / Outdoor

dedicated for the permanent outdoor
monitoring application with the
SA 271
outdoor kit. The characteristics of the outdoor
filters
depend
on
the
application:
environmental (the acoustic signal is parallel
to the microphone’s grid) or airport (the
acoustic signal is perpendicular to the
microphone’s
grid).
The
frequency
characteristic of the designed filters is given
in App.
