WIRING SIGNAL TERMINALS: ELECTRICAL CONNECTIONS IN GENERAL
❏ Using double-shielded cables:
In this case one shield is connected to the analyzer‘s housing while the other shield is
connected to the external equipment.
This gives an advantage when both instruments are supplied by different supply networks
(e.g. when installed in different buildings).
This measure is more costlybut offers best immunity against distrubances from outer fields
and from parasitic currents.
