4.1 Cable extension
Use shielded, low-capacitance extension cable. Above all the excitation cir-
cuits must have large cross-sections. HBM supplies its recommended exten-
sion cable and measuring cable by the metre.
When extending cable, ensure perfect connection with lowest possible contact
resistance and good insulation between the circuits and ground. For this
reason all connections must be soldered, or at least made with safe, stable
terminals, and installed so that they are watertight. In the open air and/or in a
damp environment, terminal boxes must be sealed.
When extending the six cores of the standard measuring cable and using a
six-wire circuit amplifier, the cable length does not affect the measuring signal.
Measuring cables should not be laid parallel to high-tension and control cir-
cuits (e.g. in common cable shafts). If this cannot be arranged, protect the
measuring cable with steel conduit and keep it at least 50 cm away from other
cables. Stray fields from transformers, motors and protective contacts are to
be avoided.
