Note: For the conformance acoustical tests with SA 271A, the Microphone compensation must
be switched On and the Field Compensation must be set to Environment or Airport (path:
<Menu> / Measurement / Comp. Filter).
Statement of performance
SV 971A working as the SLM with SA 271A meets requirements of IEC 61672:2013 for the Class 1 Group X
instruments.
Linear operating ranges with the Environment filter
The starting point at which tests of level linearity shall begin is 94.0 dB for the frequencies specifies below. For
the Low measurement range and A weighting linearity test at 31.5 Hz, the starting point is 79 dB.
