Hand tighten all screwed connections of the HF cable (2 Nm =
0.2 kg/m)! Before tightening, carefully screw on the cable by
hand.
Caution! Threaded joint jams easily.
Check occasionally if the screwed connection is still properly
tightened. If the installation is exposed to vibrations, the screwed
connection may come loose and this may result in inaccurate
measurements or corrosion of the connections.
As long as the cables are not connected, the coaxial sockets have
to be covered with plastic caps and the cable connectors have to
be protected against moisture and dirt.
