2.1.6. SA 279 - outdoor microphone protection kit
The
SA 279
outdoor kit protects the SVAN 979
preamplifier
and
microphone
from
weather
conditions. The use of the outdoor kit requires an
extension cable between the instrument and its
preamplifier (
SC 279
). The SA 279 is made of
lightweight materials and is easy to install on a tripod.
This solution is recommended for short term and
semi-permanent noise measurements in the
environment.
The outdoor microphone kit has ¾” screw on its
bottom which enables the use of standard tripods or
other user specific mountings. Technical data such
as direct and frequency characteristics associated
with the microphone are included in the SVAN 979
user manual.
As an option the user may use desiccator - Silikogel.
The
desiccator
absorbs
moisture
commonly
contained in the air. The desiccator should be
regenerated after some period of use, when it
changes colour to red, by drying it for 3 hours in a
temperature of 150
°
C. The colour of the silica gel is
visible through the hole on the top of the dessicator.
Note: See also SA 279 Assembly Guide to
learn how to assemble and disassemble the
microphone
’s outdoor protection.
Note: The correct connection of the microphone is not signalled by the controller
therefore it is recommended to perform a test measurement each time the station is
turned on.
