4.1 Cable extension

Extension cables must be shielded and of low capacitance. The supply lines in
particular should have large cross-sections.
With cable extensions, you must make sure that there is a proper connection
with minimum contact resistance and good insulation between leads and
ground. This is why all the connections should be soldered, made at least with
secure, stable terminals and given a waterproof routing. In the open air and in
a damp environment, the junction boxes should be encapsulated.
When the six wires of the standard measurement cable are extended and
when an amplifier with a six-wire configuration is used, the length of the cable
does not affect the measurement signal.
Measurement cables should not be routed parallel to power lines and control
circuits (in shared cable pits, for example). If this cannot be avoided, protect
the measurement cable with a rigid steel conduit and keep it at least 50 cm
away from the other cables. Avoid stray fields from transformers, motors and
contact switches.
