Note: See Appendix B to learn how to assemble and disassemble the
outdoor microphone kit.
Note: After assembling the SA 277 or after
calibration check that the windscreen foam
is properly installed. It should be shifted
close to the anti-bird spikes. Otherwise the
SA 277 free-field characteristics will be
different from declared ones.
For absolute certainty, push the windscreen
up to the stop.
Note: Before installing the station at the
measurement site, make sure that the
protective caps on the four antibird spikes
are removed.
It is recommended to use the protective
caps during transportation, storage and
other operations with the instrument like,
laboratory calibration, etc. to avoid personal
injury.
Note: 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.
