NPUT AND OUTPUT SOCKETS OF THE INSTRUMENT
Top cover of the instrument
The measurement Input is placed in the centre of the
instrument’s top cover. The
SV 18 microphone preamplifier
has a specially designed matching plug with a locking screw
to secure the preamplifier to the meter body. After plugging in
the preamplifier to the measurement input, the screw should
be tightened to light resistance only. Do not over tighten this
connector. It is not necessary to remove this preamplifier from
the top of the instrument unless the meter is in a calibration
laboratory as it is always used close coupled to the meter
body. The full description of the signals connected to the
sockets is given in Appendix C.
Bottom cover of the instrument
In the bottom cover, there is only one socket - USB . This
socket has a special protection cover held in place by a small
captive screw.
