SV 277 PRO User Manual
16
SVAN 977 is delivered with 16 GB micro SD-card. You may exchange it for a 128 GB
card, but before insertion the card must be formatted as FAT32.
The micro-SD Memory Card is located in the slot
under the bottom cover and can be accessed after
removing the bottom cover.
To extract the card from the card-slot, push on the
card and then pull it out of the slot.
There are two important settings, which should be assured in the instrument when it is a
part of the monitoring station:
1. The microphone compensation
should be set to
Outdoor Environment
or
Outdoor Airport
(
path: <Menu> / Measurement / Compensation
).
Both compensation filters are dedicated to the
permanent outdoor monitoring application. The
characteristics of the compensation filters
depend on the application: environmental
(acoustic signal is parallel to the microphone’s
grid) or airport (acoustic signal is perpendicular
to the microphone’s grid). The frequency
characteristics of the compensation filters are
given in Appendix C of the SVAN 977 user
manual.
2. Network
should be set to
GPRS
(
path: <Menu>
/ Instrument / Wireless Connection / Network
).
Other settings depend on the measurement and
transmission type.
All measurement, instrument and transmission settings can be set up via SVAN 977
user interface, or remotely via the SvanNET webserver or + program.
