The instrument can operate as VLM with the SV 80 general-
purpose accelerometer 100 mV/g (10 mV/ms
-2
) with the SC 27
coiled cable (see Appendix C for specification).
Chapter 16.3 presents the way of connecting the accelerometer
to the instrument.
SVAN 979 is supplied disassembled, so the user should mount the
GRAS 40AE microphone and SV 17 preamplifier on his own.
It doesn’t matter which elements will be assembled first: the microphone
with the preamplifier or the instrument with the preamplifier.
To connect the preamplifier with the microphone to the instrument, first
insert the tip of the preamplifier into the socket until the connector clicks.
Then move the preamplifier outer sleeve in the direction to the instrument
and tighten it to the screw thread.
